JC amps have great tone, and my Roland cube is great and very portable, but not very loud.
You might consider a Line 6 Spider. I have a 75w SpiderJam version with a footswitch that cost about $500 total, gives a very nice variety of clean and dirty sounds. It is lightweight, reliable, and quite loud when cranked. Has models for Blackface Twin, Deluxe, Marshall, AC30, Boogie, etc. Also sounds very good at low volumes for practicing at home, which I found nothing but a digital modeling amp will do. Even my small 6w champ style amps are uncomfortably loud when set to a good tone volume. I have my footswitch set for 2 different clean Jerry tones, a slightly gritty deluxe tone, and a screaming boogie tone with delay (tap tempo w/ foot switch).
Spiders also have 1/8" input for ipod, etc. and a headphone out. This one also has an aux 1/4" in and an XLR; have used it for acoustic solo gigs and it performs well for that also. I am listening to 7-6-90 as I type via the headphone output from my laptop into the spider 1/8 in, sounds awesome.
