Repopped 340 air cleaner

Anyone know if these repopped air cleaners are of decent quality? Should be getting my 340 back from the shop here soon and am going to be in need of one. They're priced about $100 cheaper than what I see on ebay so I figured I'd give it a shot if they aren't made out of a soda can.
