If you've got one running I find the briefcase units to be pretty damn solid! I think they start to break down when not in use but are actually pretty well built.
Mine is running, but the first IFU I bought was faulty so I had to buy another. The second IFU I bought works but audio seems to be low, not by much but I notice that I have to crank the volume on my TV by a few notches compared to other systems. Not sure if this is normal or perhaps a sign of failing caps. My CD unit has been solid for 2 years, middle gear was replaced with a bastardised version which does work fine but tends to make a bit of noise.
Frank, I'm guessing you were referring to me about getting the SGX from doujindance.
Yeah mate, the one you bought was a great deal! I had my eye on it but by the time I conjured up enough funds it was gone. I'm happy it went to you and not some bastard reseller (there's a guy who buys heaps of Duo's from Doujindance and re-sells them at incredible mark-ups).
Doujindance actually listed another SGX though, after yours, and this was the one I was referring to. He wanted $300 for it plus shipping, which would have made it close to $400 for me and that was a lot more than I was willing to spend.
