Well then ..welcome to the addiction ... as was said above get one that fits and feels good... As a begginer I would steer ya clear of Ebay and alike simply because you would be hard pressed to find a shop that will service them ... I dont know what the shop situation is like around Kelowna but it would be in your best interest to find them ... If you ever go into Calgary I would suggest that you see the Folks at Calgary Archery centre and /or JimBows Archery.
But all that said ... Find a bow that fits and a mentor/coach ... Dont be stuck on a 7" brace as was said above...while yes they are more "forgiving"
if you learn to shoot it right it wont matter .... My hunting bow has a 53/4" brace ...killed everything I shot at with it .... If you are looking for Brands to try .... I would suggest Hoyt/Reflex , Martin (the Jaguar Magnum in my opinion is the best bang for buck out there ... 305 IBO speed get into it for under 400 dollars) Bowtech/Diamond, PSE/AR ... there are some others I listed them in my personal order of liking
