Just stop by honest spazz's box of stuff, to be found at your nearest airsoft field :p
I know money is tight and the economy is bad and all that jazz, but I think you should at least try to support a good American company like Magpul. Every time you buy a knock off, how the company perceives your actions as you are giving them a big middle finger. I know it will cost more, but I try not to buy knock off gear because I want to support legit companies that come up with this good stuff in the first place. Not trying to play Big Brother here, but if you can't afford legit Magpul stuff, maybe you should put airsoft on the backburner for now and concentrate on saving up.
