Firstly, the guns you liked are priced in US dollars. Retailers in the US don't have to jump through as many loops as the Canadian Retailer(s) thus making their prices lower than ours. The kicker is, you can't order from the US because it'll likely get seized at customs and you'll get blacklisted. (Meaning everything you order from the states from then on will be searched, along with yourself if you travel over boarder)
Secondly, Kraken is being suggested because, for the price, it's a pretty alright gun (from what I've read) and is TM compatable so you can upgrade it to your liking with higher end stuff.
Take the advice of those who have made suggestions. Go for a Kraken if you don't have much to spend. It'll give you a somewhat game-able gun with the potential to upgrade when you get a bit more pocket money.
You won't be able to get much in terms of accessories/guns until you get age varified though. Once that happens you'll be exposed to a world not known by those without white bar of acceptance.
EDIT - Figures, I take so damn long to type and everyone gets in before me.
