The Micro Cube kicks out some major sound for a little amp. I got one to practice with and it sounds damn good for such a little amp. I like Ebay for buying guitars. Just bought my little sister a yamaha acoustic for 100 dollars. It arrived in great condition. If you buy on Ebay just stick with people that have %100 postive feedback. Another little thing I do to see if the people are worth buying from is to contact them with a question about the item and see how long it takes them to reply. If it takes them two days or they never respond, well then you know to stay away from those kind of folks.
