Right now my rig consists of an Alembic F-2B and SF-2. Unfortunately I'm on a tight budget and can only afford a power amp in the $300-$400 range. Any suggestions?
 
Thanks,
Connor

Glancing at Ebay I see that in the last two weeks three QSC PLX 2402s have sold in that range.  This would suggest that this is the market for that amp and that you should be able to find one fairly soon at that price.  However all three listings appeared to be from 'shops' rather than individual owners; so that may be a factor.
 
What kind of cab or cabs are you driving?  You should be looking for something that matches up with the ohm and watts ratings of your cabs.

I have a Stewart World 2.1 power amp for sale. $400.
I bought it in 2004 from Bass Northwest for $825.
Perfect condition, always in a rackcase.  
400w x 2 @ 8 ohms
650w x 2 @ 4 ohms
2100w bridged @ 4 ohms

You might find an ADA B500B bass amp. They are two amps in one and sound great.

You can find the same in USA

Find an old Trace Elliot.  They are beasts with lots of headroom.

This may be the worst idea ever but; with that kind of front end why not use a Crown USA made PA amp. Strapped or paralleled for proper match to your cabinet. I bought a Crown Com Tech 400 for under $100 shipped. This is no lightweight though. Easily 40 lbs and no knobs. It's meant to take your pre output (through whatever effects) and make it big. Crown has proprietary circuitry to protect the amp from subsonic oscillations too. Pretty tough animals.

Check out a Hartke LH500 - Bass Amplifier. The guys  at BassNW turned me on to em. They sound so much like my Alembic FX-1, I don't need to take one to gigs. Cheep, reliable, and sounds great. It is a big improvement over past Hartke ambs. $350 new and it blows doors.

Get a few of these and string 'em together~

My Crest CA9 was within your budget from ebay and is amazing. If you can deal with the weight, I highly recommend the CA6 or CA9.

I must concur with Edwin on the Crest amps. I had a CA6 and deeply regret selling it. Weight issues aside they are the stoutest amps on the market for being two space-they are deep though. I would consider putting it in it's own rack and putting your preamps and efx in another rack to distribute the weight. They're worth every penney.

I've often wondered about those Electro harmonix amps and if it is worth getting one as a backup but I assume they would get into overdrive well before getting any useful clean stage volume.  Do you have any experience of them?
