I don't think Pellet-trap is in business anymore...... their website has been defunct for quite some time.
As for the $24 B-3 from Amazon.com ,,,,,, they are great little rifles and are absolutely perfect for some to practice their tuning skills on. I have 3 of them, all home tuned, and they all turned out great. They shoot pretty decent right out of the box but with some TLC they turn into really nice little shooters quite capable of taking out small game at reasonable ranges. I've used all 3 of mine to take many a squirrel, starling and even pigeons. Get the "QF-2" tune up kit and you're all set to go. Of course remember,,,,,, build yourself a suitable "spring compressor" so that you can disassemble the gun safely. Plans for the spring compressor can be found in the the GTA Library....
