Today's higher-powered combos are great, and usually have a solid Direct Out (xlr output) included for sending a good signal direct to FOH, etc.
I tried and did not jive with the Rumbles myself and prefer the flavor of the Ampeg RB line. That's just personal preference, though. The 115 or 210 version of any current, quality combo (Fender, Ampeg, GK, Hartke, Ashdown, Boss, etc.) will work great for solo practice or with a band, and could easily carry most club gigs.
While I currently run separates for shows, I do band practices with just the RB110. (50w, 10" speaker) I wouldn't recommend that as someone's ONLY amp, but am impressed with how it keeps up with a drummer and 2 guitars.
$1k can get you a LOT in the combo world.
My pick, if I were buying an amp today for my own purposes, would be either an Ampeg RB210 or the RB115. I think either would handily cover 75% of my gigs right now, and 100% of my practice situations for under $700 brand new.
For something a little different, I'd like to try out a GK MB112. They're pricier, at $800 for a 200w 112 combo, but I think you might end up with a little more clarity with the GK, based on my experience with my Legacy 800 and Neo 112II cabs.
Are you planning on using any preamp, eq, or effects pedals? Some of the bigger combos come with more tone control and overdrive options built-in. If you want those, fine, but realize that you can always toss a pedal or two (compressor, eq, drive/overdrives, etc) upstream to achieve the sounds you want from just about anything.
One other idea here to mention: the more "color" or pronounced of a specific tonal profile a given amp has, it may be harder for that amp achieve DIFFERENT sounds if you are trying to jump genres, etc. If that is something you are expecting to do in college, you may want to find a neutral sounding amp as a starting point. I feel like both the Ampeg and Fender amps have a pretty strong "baked-in" sound. That's not necessarily bad, just something to think of. I've found most current Hartke amps to be a little more neutral.
I'd just go try out as many as you can and pick what you had the most fun playing. Good luck and let us know what you choose!
