Nick,

Greetings

I am very much a tinkerer, but would still recommend the SMS-1 over the Behringer route. By the time you buy the Behringer unit, buy the flat response testing microphone, deal with external sound cards, then preamps(yes Nick, you're going to need a preamp), then cables, cable adapters, then trips to buy this stuff....you're just not that far apart from the actual dollars of a SMS-1(when purchased at the lower end of its price range). In my limited experience doing it both ways, the SMS-1 sounds better(with the latest software). With the Behringer method you will also have to deal with microphone calibration files system files and learning curves with both REW and the Behringer unit.
