I bought mine for 99 buck a while back. They are a heck of a lot of fun, not very practical but fun.
$350??? would I pay that if I didn't already have one. Depends, I done some dump stuff over the years, paid some outrageous prices for stuff I didn't need.
So if I didn't have one, and the cheap ones were gone, yeah I'd probably pay that on a whim.
My next dumb stunt will more then likely be paying too much for a S&W M1917. I had one a long time ago that was stolen. Now that I'm really heavy in to surplus US Military Rifles I got to have another one.
I'm not very smart sometimes. But my greatest fear is dying with money in the bank.
