I too am on the hunt for a three mic mixer. I did some digging through the boards but found no solid feedack on either the Sd 302 or the PSC DV Promix 3. I am fairly certain that the Sound devices 302 is the way to go, but the price tag is a bit steep for this time of year, and the PSC product is a LOT cheaper, but the whole "get what you pay for" thing is bugging me.
Anyone have any experience with these devices?
