Well I have to weigh in here as this also seems to be excessively priced for what you get. I am very happy with all of my squeezeboxes (2), transporter, boom and duet. All run just fine and there is no lag when running squeezecenter (Now Squeezebox Server 7.4 although I am still currently running 7.3.4) off of the iMac (2GB RAM all music on one NAS). I also run my home office SB3 through a Musiland SRC-10 upsampler and then into the external DAC. This to me sounds better and has the advantage of using BNC for the output to the DAC (although that is not an option right now as my Buffalo32 is still partially [mostly] in pieces). Right now the only advantage the transporter has is that it can process native 24/96 files but the SB3 cannot.
