On the subject of drivers, I really really like the IMS drives (IM483 and IM805). Very well engineering/build professional units, and handle a good bit of power. Even better, I can get support on these (which I needed some time ago when we thought we fried a couple). Downside is they're expensive (~$250 ea), but are always on ebay for far less -- got some used IM483's for $45 and some new ones for $79 ea. Also got some used IM805's for ~$80 shipped recently. By now I've accumulated 5 IM805's, 5 IM483's and no I am not affiliated with IMS in any way.
