I have a Carvin DCM1500, two years old, just gigged a couple of times (non-smoking), mainly used in the house and studio. I'd like to swap it for a DCM600, as I don't need the extra power of the 1500. The 600 would be just about right for what I'd be doing. If your DCM600 is in comparable condition, hasn't been gigged much either, and is a couple of years old or so at most, let me know. I'm thinking around $100 for boot.
