I'll go first, 4-wheel parts, the one in SLC was very friendly to me, and gave me a huge credit line when I got my first Jeep, and before I found RME. I dumped a lot of money into my Jeep I wished I hadn't but it wasn't their fault. Year and half later my pinion nut came loose, don't know if it was their fault or not, they said they would replace parts but I would have to buy install kit and pay labor (About $400). I chose not to do it.
Anarchy Offrroad has been extremely friendly to me. I have never purchased anything from Brandon but have called him on several occasions and e-mailed him. He has always been willing to talk and give me his opinion on what would work best. Seems like he knows what he is doing.
Rocklogic, my first and only experience with them was a couple of months ago when I stopped by to discussed the possibility of putting a Toyota axle underneath my TJ. Von was extremely friendly. He gave me lots of time, wrote down everything I need and the best places to get them and even gave me estimated prices of what the used parts would cost me. He informed me of what Rocklogic could do for me and that if I wanted to do it myself that he was there to answer my questions. My wife even commented how friendly and helpful he was.
Factory Tubular, I only stopped by there one time. The guys there took me out back and showed me some of their projects they were working on. The projects were very impressive. The guys were very friendly. They seemed to have a very large assortment of tabs and things like that.
Sky's Extreme, I stopped by there once to talk to them and they looked at me like I was disturbing them. I asked them some questions and they gave me an answer that was very vague and I left with a feeling like they were a bunch of kids that made a business so they could play on their toys when they wanted too, now let me add that was five years ago and I seem to remember them saying the boss wasn't there.
OK there is my list
