Pro PA Amp Recommendation

A fellow audiophile friend and I are amateur musicians and are looking to buy a power amp and PA cabinets for use in a basement and light outdoor settings. (We have a mixing board and effects already.) Do any of you other audiophile/musicians have any recommendations for amps and speakers for this applications?

We are looking to spend around $1000 for the combination and sound quality is as important to us as quantity. We also don't need extremely heavy duty stuff since we won't be hauling it all over the place on a regular basis.

Thanks for any ideas.
Crown is a good choice.
QSC also makes good PA amps. The PLX series has a switching power supply and only weighs around 25#. Very good sound quality also.
I would recommend Mackie amps and Community XLT series of PA cabinents. The models I own and used in our rehersal studio and on the road for over three years with no problems are the M-1400i amps (3 of them), XLT46 (3 way speaker) and the XLT415 (4 - 15 in. subs powered by an older QSC 85 pound monster, the subs stays in the studio when we play out in bars but enjoys the outdoors). Other cabinents in our arsenal are by E/V. Good brands of PA cabinents are E/V, JBL; great ones: EAW and Meyer Sound to name a few.
Keep Rockin'

I have used a number of pro PA amps, and to me, it is hard to beat QSC's PLX line. Their combination of power, clean sound, reliability, and light weight is excellent, especially considering the price point. Crown makes a number of great amps as well. I use a PLX 3002 in my bass rig (3,000 watts into 4 ohm, bridged mono!), and it allows me to have gobs of headroom without breaking my back!
