Rev-N-ator ignition boxes?

does the rev-n-ator have any kind of warranty? I always thought wells made good ignition parts, i currently have a 4 pin wells module right now, if it pulls timing out at 3200 to 3600 rpm then that sucks, i paid 50 bucks for the wells module i have, but i guess its a hunk of junk to say the least. I'm still debating over the rev-n-ator or don's box from fbo systems, i like don's 2 year warranty and the fact that it has a rev limiter as well and the ballast resistor can be eliminated, but the storys i have read about people not being able to get don's box to perform for very long if even at all kind of scare me away from it... I've been told don's box is a 4 pin Hei module in a fancy billet case with a rev limiter on it. So i guess making sure its in a cool enviorment and making sure it gets fed a solid 12 to 14 volts would be very important in keeping it running, on the other hand the Rev-n-ator has a rev limiter and is supposidly new digital technology that doesnt pull timing out but still requires the use of a ballast on the street and the rev-n-ator is about 20 bucks cheaper then don's box.

So,what leads you to believe your Wells box is a hunk of junk ?
