I appreciate everyones input, it is very helpful. I am leaning more towards an M15 Carbine now after doing some more reading, seems to be a lot more in the way of mods internal and external plus they seem to be quite popular for good reason. I will keep my eyes open for a G&P as well as a CA on the forums for sure (If someone has either in an M15 variant in Winnipeg they wouldn't mind showing me let me know). I would rather spend a bit more money up front and not have to deal with as many repairs etc.
Alpine - Check the name pal, I got AV'd on the weekend :P
