pops,
I know! It's one reason I've been so shy on putting one of my Thiels up for sale. Given the fact they seem to have dried up on the used market in terms of availability, it feels like it would be quite a final decision to get rid of my 3.7s. Unlike, say, Quads or something that you'll always be able to find easily again.
BTW, I contacted Rob Gillum and he has all the drivers for the Thiels, including the 2.7s. That's good for me as I'm pretty much convinced I won't be giving up these 2.7s. They sound glorious and look perfect in my room - I'd never find another pair on the ebony finish. So I may grab a spare coax/woofer/passive radiator for the 2.7s, and if I keep the 3.7s I might do the same for them.
