The previous post by AVguy makes a good point: moderately priced tube amps can, and usually do, sound quite different than comparably priced solid state amps (due mainly to the much higher cost for transformers in the tube amps). The performance difference between tube and solid state amps have been narrowing over the past 10 years, but that's mainly true for the higher-priced models.
If you want to experiment with a tube amp, you might look for a used Quicksilver amp, which is user-friendly and offers good performance for the money. You might also consider some of the very good tube amps now being made in Asia (mainly China and Taiwan), which offer good value due to their lower manufacturing costs.
