http://www.thezeb.com has a few good deals going on right now. Depends which solobaric you have as to what amp I'd go with though. do you have the dual 4 ohm or dual 2 ohm?

$369 for a 900w orion amp would be great for the dual 2s
for $329 you can get a harrison labs audio engine with 800wRms that would make that solo humm, and you can pick your optimal impedance. THey may not look like conventional amps, but they kick ass

they also have a refurbished hifonics zeus xi on sale for $359 that will do 1200w x 1 @ 2ohms and will pump the crap out of that solobaric, it has full warranty and everything and would be great for hte dual 4 ohm solo.
