Get either the Rack + (for the 8 preamps/DIs) OR the Profire 2626 +PT MP8, or Used 002 rack, get it modded and PT 8 upgrade.
I do think the 003 line is way overpriced. The preamps and converters are greatly improved from the 002 line, and there's a few other nice features on the front panel, but still at least $500 overpriced.
