Hi - might want to check out CProducts

Highly recommended on several sites, 20 and 30 round magazines, a variety of coatings, springs, followers, aluminum or stainless steel bodies (these have been given very high marks on lightfighter.net). For aluminum-bodied magazines, you can buy their new magazines for close to what some used or crap magazines are going for. You can also email or call them up and actually talk to someone who knows what they're doing at their company. Good luck.
