I've found the TacSol Cascade .22lr down towards $100, which beats every last rimfire can I've ever seen. The YHM Mite used to be the least expensive, quality rimfire can around, but I can't find it anywhere near the mid to low 100s like the Cascade. The YHM is alumn/stainless steel AFAIK, the Cascade is alumn/titanium. I posted a thread asking for comments about it, but nobody has much experience with it at all. SilencerTalk of course has a few guys that own this can and they really like it. I figure, I'll get one and write a review on it. For as cheap as they are selling for, I don't see any reason not to just get one while their priced this low.
