Err, all of the above, and then some?
It was next to impossible to get him on the phone, and when you did it was always some excuse about how he hadn't had any time to do this or that, it'll be ready soon, etc.
Eventually you just give up waiting on the parts you sent him and buy another set so you can get to riding again...and that leads to "Well I don't remember you sending me this or that..."
At the very least you could expect a 6-12m wait for a pipe you already paid for (had to get enough customers to prepay so Shearer would build another run of pipes for him).

He started out small on an old forum, gained some followers, and started a new forum (QRHQ).
Supposedly he did pretty much every go-fast mod for the LT's, but in truth was just farming it out to other people and calling it his own.
He had a few specs that were his "secret", and nobody else could do the work.
The fan base that he accrued would have made him some real money had he been a better businessman with ethics.
He ran a pretty shady business, wouldn't honor complaints, customers often "lost" parts that were sent to him, and then there was SCAMMY, but that's another story for another time.
It got to the point that the guys who supported him were next to nil because he burned nearly every one of them in some form or another.
So he shut the site down and we were homeless for a bit until we all converged here.
Supposedly he's turned over a new leaf, but that's yet to be seen.
Here lately there have been a few customers he's done right by...don't know about you but snakebites don't heal very well on me.

So, instead of dealing with a flaky middleman, just go straight to the source
