Omni Top 12 and power ?

[Brew]

Finished OT12,and perform as advertised. Very clear, ample bass, great mids-highs. Testing with <100 watts..well it brought the neighbors out. Very loud with no distortion.
Fitted with Deltalite 12,crossfire 1016's 3per bank, necked horn,filler, and piezeo resister/woofer filter.
It is finished with Duratex, corner guards, and for fun, a grill covered with OEM Fender silver/black wooven cloth.
Use wil be primarily as a cab for guitar working through a line6, in small clubs,and occasionaly as music PA.
Where I need help is determing most suitable power amp and eq. Want amp I can grow with, maybe additional OT12 and bass bin. but need to be prudent with cost.
Mind is muddled with trying to find not to much....not enough...
$$.
Thanks for your thoughts.

For your guitar backline use, I'd look at picking up a Crate Power Block from Ebay. Small enough and cheap enough to hang onto as a spare, if/when you upgrade. You can use the FX in or aux in to use just the power amp, and in a pinch if your Line 6 dies you've got a backup guitar amp. I've been wanting to get one for a while, just to have as a "swiss army knife" to use for guitar, bass, pa etc. - 150w RMS in mono, about 4 lbs and the size of a small book.
