hey all, I've always looked around the used market for reworking my rig. In the past, I always saw a wealth of SVT 3Pro's up for sale, and 4Pro's hard to come by. However, now I'm rarely seeing any 3Pro's around, and a lot more 4Pro's being put up for resale...7Pro's are also typically available used when I search. Anyone have any thoughts? Seeing the same thing? I'm wondering if it's just the market, or other variables?
