I have one of the very early models when they were made by Mr Fast Eddy himself that has been a pretty good cooker. Mine was made in 1992 and is still working fine although I do have to work on it once in a while. Fast Eddy at this time had a deal with Traeger to use all their parts and running gear so it is easy to get parts for my cooker. He sold his rights to Cookshack and they continue to make this fine cooker and have made some great changes to them over the years and if it was me, I would go to their forum to get any information on the one on Craigs list. The controllers have been changed a couple of times and I would want to know the year of the cooker to see if it had the better controller on it. The pellet delivery system has been changed as well and this is another item I would want to know about. These are fine cookers and used in BBQ Competition over the years and have probably won as many contest as any other cooker out there. They are also BOH approved and can be used in about any commercial setting. They do need to be kept clean or there is a danger of fire in a commercial setting but many restaurants are still using them and like them. Great capacity, all Stainless Steel, low operating expense, dependable, great company to deal with, and a reasonable purchase price as compared to most BOH approved cookers out there. They are have a big brother and it is the FEC 120 that is also a great commercial cooker. The firepot is on the outside on this cooker and is less likely for any fire danger. Neither of them pose any fire threat if you do keep them clean. The value of the cooker would depend on the year of origin so be great if you could find that out. Not really much that can go wrong with them as they are dirt simple and being SS will last a long time. Mine is 26 years old and still gives me good service.
