I was influenced by Warren and many positive Gearslutz reviews to buy a used BAE dual MPF and a DMP, last year. Paid $1750 for the Dual MPF, with power supply! So far, I love both and am really happy with the purchase. I've used them on Vocals, Guitars, Bass, Keys, and Roland E-Drums with great effect. I would like three more channels, when funds permit.
I am also thinking of getting a pair of CAPI VP-28s, next. This will be my first 500 series experience. I needs more channels for drums set and hear these are great on toms.
