I have the 603's and I LOVE them for overheads. So far, it's been my favorite overhead.You can pick up a pair of them for about $150 new.
I bought mine through
8th. street music in Philly. Their website is great, and they have good prices on a lot of the mics.
I also picked up 3 AT Pro25 kick mic's (I use them for toms) for $50 each.
