I'm thinking that your lack of responses on each post are due to a lack of clarification on what you plan to use these for. What is your current setup and what are you planning on using this device to record? Got a DAW already? (If not, Reaper is a good, cheap option that's touted around here) I've never had any experience with any Sound Devices gear so I can not give any advice other than to give more information so that others on here know more about the particulars of what you plan to do.
I actually just got an email from Steinberg this morning in regards to that new interface. It's on the market and it's listed at $200 here in the US. It's packed with quite a few nice features though, could be a really good option for the OP.And! There is a new Steinberg coming along soon. 2 in 2 out, MIDI and "i" support but most interesting perhaps, on board DSP and likely around £160.
