I by no means have an unlimited budget. I often have to sell hobby stuff to get more hobby stuff. I do however see the value in things - not to say cheap options have no value because I'm not saying that at all. The dollar is what you spend, the value is what you get. In a my of cases, the aftermarket stuff is a better value than the OEM stuff - especially if you're talking OEM OS stuff.
FWIW, there are several .46 sized mufflers on eBay for $20-25 plus shipping. One is an OS 744 for $20.
