Welcome, glad to have you as part of the Freaks...
as far as best products, my favorites are always Finest, Platinum or Topps Chrome. But as far as bang for the buck, it seems Platinums pretty good for the price. Finest is good when it first comes out, but the price jumps alittle too fast for the value. for some reason topps chrome jumped in value way too much to say its worth it to me. but if you search around and find good prices then those are all good valued products.
