First off, shop used if you're comfortable with that, as your money will go a lot further. Second, listen before you buy...don't want to buy a speaker cab that somebody swapped Radio Shack drivers into after they toasted the originals. I'm not sure what "medium sized" to you is, but realize you need much more outdoors to achieve the same SPL's as inside. Some suggestions:
- The aforementioned Presonus 16:4:2 is a great all-around board...definitley a great choice for small-time bands.
- Look for used upper-range gear- Peavey QW, EV QRX, JBL SRX, Yorkville Elite or Unity series, Community SL, even Carvin TRX.
- Regardless of my opinion of them, the Behringer DCX2496 is a very good processor offering quite a bit more bang-for-your buck and features than a Drive-Rack costing much more. That being said a Drive Rack 260 can be found used at a pretty good price sometimes, otherwise I'd just get the Behr. My band's been using one for 3 years with our rig and it's been perfect.
- Amps...stick with name brand. Peavey, Crest Pro, Crown, QSC. We run two PLX3402's and a PL6. Rock solid.
- Budget plenty for road cases and cabling. You rig will look like trash and you'll be replacing gear left and right if you don't protect the gear from the road.
