Some questions How loud do you wanna be? How much do you wanna pay? How much do you want to buy new versus used? You can get a decent used tube amp for about two bills if you look hard, but probably not more than 15 watts. Plenty for practice, small gigs. I used a Pro Junior for gigging and did fine with it, micing it when/if needed. If you want loud, you need to graduate to 30W or more, and be ready to shell out more $.
