For prototyping, good enough, but the tolerances were sloppy.

I've had metalphoto screw up enough orders that I'm ready to try something else! They're not -terrible- but they can't guarantee a tight tolerance and it always bugs me at least, drives me nuts at the most. <br>
<br>
If you've given it a shot, where has it worked out for you? <br>
