I think you're on the right track in trying out as many as you can. I have collected several amps over the years, both tube and solid state. There are many great low wattage tube ampsout there in the 15w to 30w range, which are plenty loud enough for your needs, or can be "mic d". My personal preference is the Ibanez Tube Screamer TS15H- 15 watt all tube head with built in Tube Screamer, but there Hughes and Kettner is a great, versatile camp, as is the Egnator Tweaker 15 and the Black stars are very good. If you have the money, the Fender Deluxe Reverb '65 Reissue (I believe you mentioned) is a superb amp- one of the most widely used and recorded amps in the industry. the fun part is the shopping and testing.
