Re FPS: I would call/message TA they'll be able to tell you what it's shooting at as well as change the FPS for you if you want. Often times Canadian retailers have to change the "stock" FPS when importing guns.
That gun should fit a 9.6v stick if you're going nimh, or a 7.4v 1000-1200mah lipo

I wouldn't say the G&P is a bad buy, but IMO Real Sword and LCT make the best AKs on the market. Real Sword may be difficult to find and potentially out of your price range but an LCT AK is something you should consider. They don't make one exactly like that but they have several tactical style AKs if that's what you're into. Just stay away from the under-fold stocks.
