I have an early Technium 440 I picked up at ReStore for $70.
It still had the original tires on it and a sofa for a saddle. I hate stem shifters, so I went with bar-ends. I also just wrapped over the foam crap on the bars because it wasn't coming off without a fight. Anyway, it rides similar to my Miyata 710 and 600GT and I've seen no indication of separation at the lugs.
I did have a Miyata CarbonTech 3000. I got the frame for a song because it was built without shift lugs or cable guides. A friend who did CF layups patched it up where the holes were. I built a 18 lb fixed gear and rode the piss out of it. A guy came by with an open wallet and went home with it.
