It has been well documented that Steve and Ed worked together at one time. Ed is a little hard to explain. Basically he has his own clientele and from all that I can gather he does very well and there is a long waiting period if you wish to utilize his services. He has the reputation of being very thorough and quite expensive. He can be quite rude at times and he can be very friendly at other times. He was the first president of the DOA and has a very strong ongoing influence in shaping it's destiny. As to DMC Houston, very straight arrow, willingly helps anyone who asks, has the largest supply of parts and works at creating replacement parts where original items are no longer available. There is much cooperation between all of the vendors, except for D-1. I think that's common knowledge. As to where to go for service, it has been suggested that several factors determine. Most who deal with D-1 are very pleased with their dealings, not everyone, but not everyone would be pleased by anyone. That's also true of Houston. Now, as to who is top gun, it depends upon your individual experience with a given vendor. Most are regular contributors on the list and advertise regularly in the World. In CA, along with D-1, there is Don Steger who has a lot of experience and a well pleased following. In the east is PJ Grady where seldom a bad word is heard (except today on a posting). There is also DMC Joe with a tremendous amount of experience. I think these are the biggest of the big guns. For information and parts, Darryl Tinnerstet (Washington) is one of the most knowledgeable; John Hervey (Texas), especially in electrical parts (but not solely) is very responsive; Bob Miller also has a lot of smarts and parts. The usual disclaimer, I haven't dealt with everyone, these are the ones I have first hand knowledge of, all have treated me well.. [Moderator Note: just to be clear, this was posted by Les Huskins]
