It is a Honda EM1800. Been a killer generator and I only use it at the track. Well, I actually used it to run our freezer once when the power went out at our house. Anyways, it isn't a quiet model like the 3000i is, etc. However, plenty of grunt to run warmers and a fan, etc. Absolutley an endurance must have... Anyone interested, PM me offers. I really don't know what it is worth. I just bought one of the 3000i models and can tell you they aren't cheap new... The dealer didn't take trades so... You guys probably know more than I do. Never had race fuel in it and always had 93 octane running in it since it was the pump gas we usually carry... Oil is good and has been a great asset everytime we've used it. I'm in Ohio so, I can get it to anyone in the state, but have enough guys I know running the WERA Nationals and regionals, I could easily get it to them to get to you. I also instruct at the Mid-Ohio STT events and it will be there until sold. Here's a pic of the thing: http://www.foremansinc.com/power_equ..._generator.htm
