Louise, knowing you are from calgary and another Canadian changes things.
Aerogarden's canadian website charges sizable shipping and are priced in USD. Having gotton some replacements from them, I think shipping from US would take 3-4 weeks, maybe less due you promixity to Colorado but there is usually delay at customs.
To compare prices, you can look at both AG Canada in USD plus shipping converted and Eco-Source for C$ + $20 shippinghttp://www.aerogardendirect.ca/promotion/index.php?promoName=catalog&pageName=homepage&r=1http://eco-source.easystorecreator.com/
Your best bet would be to find one locally in Calgary, so look up with your postal code at http://www.aerogrow.com/store-locator/store-locator-landing-ca.php
and maybe let your fingers do the walking and call them to see what they have in stock.
I used Hyatt calgary's postal code and only found 14 sellers and 5 are defunct Linens n Things and 9 are Canadian Tire.
Canadian tire tend to carry them, at least in Ontario so you can also use their website and use inventory checking ability to see if there is one in stock. Space Saver 6 tend to be C$ 149 plus tax there and AG3 (small one typically used for flowers are a little overpriced at $99 plus tax.
In Canada definitely a 6 pod model since 7 pod kits and accessories are harder to find and you almost always have to pay shipping. I doubt you would find in stock at local retail that you can walk in a garden starting tray (i.e. seed starting kit)http://www.aerogardendirect.ca/promotion/index.php?promoName=catalog&pageName=product&viewProduct=0069-00Z
or Deluxe Master Gardener Kithttp://www.aerogardendirect.ca/promotion/index.php?promoName=catalog&pageName=product&viewProduct=0529-00Z
Shipping is difficult from US and may be time consuming. Considering it is now mid April that is pretty tight for early June transplanting, if it takes 2-4 weeks to ship from US.
To understand your situation and best choice, is price a big considertion? Do you see yourself potentially having more than 1 AG in the future ?
Your practical choices are down to 3 6 pod models:
1. Elite + - the taller model can potentially grow tomatoes and pepper to maturity - may be difficult to find in Canada, likely to need it shipped.
2. Space Saver 6 SS6 is more easily available via Canadian Tire but will not grow full sized vegetables, maybe some minis tomatoes and peppers with heavy pruning and lots of care with probably only 2 plants in the machine.
3. Aerogarden 6. The Elite is a regular height model with some metallic paint / trim and not really worth the extra money over the regular Aergarden 6 unless you are willing to pay a premium for how it looks.
So if price is a driving factor, buy a SS6 from Canadian tire for C$149 and 1-2 seed kits and just try to use a similar kit to what you want and pick out the seeds if you can. Total all in cost $170-200 plus tax.
If price is not an issue and you are willing to pay shipping, buy an Elite with mega cherry tomato kit + from EcoSource for C$249 https://eco-source.storesecured.com/items/indoor-gardening/indoor-aeroponic-gardens/aerogarden-6-elite-plus-br-with-mega-tomato-seed-kit-br-and-trellis-system-included-ag6ep-detail.htm
and a 7 pods starting tray and cut it to size for $37https://eco-source.storesecured.com/items/indoor-gardening/indoor-garden-accessories-and-replacement-parts/aerogarden-starting-tray-agst-detail.htm
and the 7 pod garden
and maybe a deluxe master gardener kit for C$50https://eco-source.storesecured.com/items/indoor-gardening/indoor-gardens-seed-kits/master-gardener-br-deluxe-kit-br-for-aerogarden-3-or-6-pod-br-new-product-agmg6-detail.htm
For total costs around C$300-400 plus tax after shipping.
Option number 2 of AG6 with the gourmet herb kit plus a garden starting tray is a middle ground and can be done for around C$210 + shiping and tax.
If you want to start tomatoes for outside, tomato kit is kind of expansive since it only comes with 3 plants and 3 spacers but have good nutrient for a first timer. For a first indoor tomato plant the cherry tomato kit is a good idea. For tomato starting for outside, seed starter tray, master gardener kit or modified pods of a purchased herb seed kit may be a better idea.
Hope this helps...
