I borrowed a blues Junior a few years ago, I thought it sounded OK, but it burst into flames :-(. I watched the repair guy fix it, and the standard of construction on the outside is a lot better than the inside. It was really built down to a price.
I ended up with a Cornell Romany, no FX loop, but sounds good and has a useful power scaling function. The EQ bypass gives it a very different voice, which is useful when recording.
I've too have been after something with an FX loop....the Fender Supersonic 22 looks good, but i've not tried it, and I never hear it sound really good on youtube demo's. The most interesting amp I tried of that ilk was a Bogner Duende...it was really nice, quite expensive, but a bit different to the run of the mill. The example I played was a bit tatty (it looked like it had been in the shop for ages), otherwise I'd have gone for it.
If your anywhere near the East Midlands, you'd be welcome to check out the Cornell.
