Don't forget the Palmer Blazer...
Often described as the gun that autocockers wished they were.
However not as good a platform if you're the type who wants to replace half the parts down the line or fiddle with fine tune adjustment. They're a gun you buy, leave alone, and if it gets sick you send it home for a tune up. Though they're quite reliable (if you don't fiddle with it), so you don't have to send them home very often.
You also have the ATS line of guns...
Probably not what you're looking for, but I'm a fan and the company is local to me so I have to give them a mention. Built like a swiss watch. They just sing when they work (well, more of a Bark really, but you flip on that mechanical full auto and everyones head turns), but if something goes wrong you might need a magnifying glass and a tweezers. Lots a little fine parts. Great gun if you enjoy difficult puzzles.
I do believe you can still buy new Ice Epics...
Very small, very light, very compact, rather interesting boltless trapdoor design. You'll definitely turn a few heads, but being rather rare on the field if something goes wrong you'll be on your own. I'd call before ordering on-line, just in case.
