I think if you do much reading on this site you will find most all the "smiths" that participate on this forum are well respected and do great work. If any of them did bad work you will find that too. But, IMO, just about all of the guys around LRH are very good.
I've bought parts, have builds currently going or acquired information from Shawn Carlock w/Defensive Edge, Kirby Allen W/APS, Kevin Cram W/Montour County Custom Rifles
, Travis Redell W/ R Bros Rifles and Jerry W/ J E Customs. These are the guys I've personally dealt with and ALL were great.
I'm sure there are others here that are equally as good but this is my personal list of dealings.
