If you want inexpensive and fun to get into it, I would recommend two amps. I have both of these and that is what got me started on tubes.
Tube Cube 7 if you have very efficient speakers. It has a better model of tubes than the current miniwatts, so better rolling options if you like.
Aiqin/Oldchen EL34 amp - discussion here - twice the power, nicely built, quite affordable.
