KP174,
I own 2 RNC's, as well as a Behringer Multicom Pro and an Aphex 108 Dual. I always reach for the RNC's first, but the Behringer doesn't sound bad at all for certain apps, it all depends on your circumstances...How many comps do you/will you need? You might find the 4 comps in a one rackspace unit (Behringer) a great bang for the buck (like I did) for non-crucial use, or you might prefer to spend your $ on less comp channels with a better sound. I love the RNC's, but have to say the Behringer surprised me, I expected worse for the $...as for the Aphex, sometimes a bit noisy. Oh yeah, I have a Joe Meek VC1Q that I use the compression on as well, I highly recommend the Meek compression if you need some heavy-handed "effect" style comp'ing, again for the price, I know there's always better for the money, except maybe in the RNC case!
