Gee, it really depnds on what you need for volume level and what kind of venues you'll play at, as well as whether or not there would be PA support. You might do ok with the smaller stuff for bluegrass and jazz, but a rock gig will require more. I have a CMD 121H combo, but it isn't enough for rock, even in small venues (unless we're VERY quiet---which ain't the case). In order (for me) to do rock I had to go to a 115 cab, actually two sometimes. Personally, I chose a Little Mark III head and two Traveler 151P cabs. I get by with one cab for most club gigs, but bigger rooms and outdoor gigs are best with both cabs. (btw, it's not because of te 15 so much as it's about the cab size, although the 15 IS more robust than the 12 in my 121H). That's just me, though. In my experience, I want at least 300w at 8 ohms with one speaker for most of my gigs. Also, the one speaker must have enough excursion to accomodate what I'll put through it. Your budget may be too low for an effective rock rig. My LMIII head and both cabs were $1800. You might wanna look at used stuff for better prices. btw, the Jeff Berlin combo is a goodun, but it's out of your budget, unless used.
But, hey, are you in a band, or are you looking for something to get started with?
Anyway, the rigs you mentioned are all good, but each has its merits and limitations.
