for gigs I use a bf super compact with a bf midget. Really easy to carry individually and they stack well. I can fill a small hall with a gk mb200, at a push. Gk mb500 fusion is more than enough for any gig I've done. The midget on its own keeps up with a loud drum kit so fine for rehearsals and really easy to carry.
The only drawback gigging I've found is I can mess with the eq for quite some time until I get a nice fenderesque thump. I've just got a darkglass head with cab sim built in, you can turn it off if you want clean, it seems to go well with the bf cabs but no gigs yet, so only tried it in my living room so far.
Having read the thread I really don't rate trying cabs/amps out in shops. They never sound the same when there's no band. I buy second hand, and if I don't get on with it sell it on. I might loose a bit of cash, but nothing like as much as buying new, and it's a lot less nerve racking.
Oh, the other thing about bf cabs is they do need breaking in, they sound much better after a few hours of hard playing. I don't know if that's true for all cabs. Good luck!
