Following Calkulin's lead, I have also sourced the parts from the clutch sold by HS Tuning. As far as I can tell these are the same parts. The clutch will be installed this weekend (I hope) so I will be able to update as I go.
The most troublesome and frustrating part to get was the pressure plate from PartSale out of Estonia which took almost 8 weeks to get here (240 Euros delivered). Their version of customer service is a far cry from what we're accustomed to in the US. In fact, after they had shipped the part they actually emailed me asking that I send the replaced parts to them... something about an exchange program they had failed to tell me up front. I told them I'd be happy to send them the part back as long as they pay shipping and handling... Havent' heard from them yet and I would suggest finding another source for that part.
Spareto for the disk - also from Estonia (I think): $195 super easy to deal with online.
AutoHausAZ for slave cylinder and pressure plate bolts: $93 also very easy to work with
Other bolts from Audi:$10
Total: $613 delivered. Not a bad deal in the end.
