Might have a Memphis MCD500 for $205 shipped. Will have to make sure since it's a friend's amp. He asked me to look for something with more power last week but let me know if you're interested.

Johnson & Faber - thanks for the offers but a bit over my price range - lookign for something as close to $100 as possible (since it's only a stand in amp) - again thanks for the offers
