I recently was involved with buying so decent quality gear as a start to building up a PA for use for community events. The music mostly going through it was going to be folk.
In the end, after much discussion, we decided to buy desk, Fx, graphics, mics, DIs, stands, cables, multi-core, and flightcases. We spent £7000 on it of which £700 was cabling (excluding multi-core) and connectors. At this point in time we're still hiring the speakers, but in a couple of years we're hopefully going to have recouped enough to buy some. We save in the long run, and we did get half of it funded, but still, you can spend an awful lot.
I'd agree looking at the db technologies stuff. They are generally good at the more budget end.
More information about what exactly you want to achieve would make us able to better advice.
