Getting better, huh? Good to hear, Lefty! Keep up the good work!
Based on what you've told me, I would suggest a Fender Frontman 25R (25watts, 10" speaker, clean and overdrive channels with reverb) DEMO here: http://www.youtube.com/watch?v=PJY8b6RtcT8
If effects are a big deal, I'd suggest one of the smaller Roland Cube amps (Models of many "big name" amps with clean and overdriven sounds, chorus/flange/phase/tremolo FX, delay, and reverb... speaker size and wattage depends on the model). Demo HERE: http://www.youtube.com/watch?v=Qygpkj6rDzo
I can't personally recommend Line 6 amps, because I've not had much experience with them. I've pretty much stuck with Fender amps as long as I can remember (except my first amp, which was a "Pignose" 7-100... one volume knob, killer vintage tone. DEMO: http://www.youtube.com/watch?v=U_t5dX_YonA) and only tried the Roland Cube at the urging of a friend who owned one... I set his Cube to the "Black Panel" amp model with a bit of reverb, and it sounded so much like my Fender Twin, I got goosebumps. No lie!
This post turned out a bit long, but I hope you find some of it helpful.
