Haven't seen one lately, but I will keep an eye out.
Definately visit the open air photo trade show in Doesburg late 
August.
Btw, for those with a Rollei 600x system: I spotted a used Rollei 70mm
back again, this time for about US$1500. Although a bargain compared 
to new price, it is still pretty stiff considering that the Mamiya 
back cost only US$1000 new....8-))

I have a Kindermann set, but only the reel is steel, the tank is
plastic. Hewes also makes SS reels for 70mm, but no tanks (I believe
they fit Jobo drums). Always keep an eye out for those, these
Kindermann's are *very* expensive new, but you can sometimes find
them on photo trade shows for 1/10th of the price.

Check Dan Eisenmann's postings on rec.photo.marketplace, he sells 
one-time used cartridges for US$12; but I bought about 20 well-used 
ones from him for US$80 or so. He might still have some of these from 
time to time too.
Yes, more cartridges does seem useful, as you don't want to thaw and 
refreeze the bulk roll every time you need a cartridge. Also a matter 
of efficiency....once you have the cutting procedure sorted out, you 
might as well fill a bunch of cartridges.

Bronica sells a nice High Eye Point viewfinder for the ETRSi....might 
be useful for this application....
Doesn't the ETRS come with a waist level finder

Check my homepage for some stock numbers, URL in the footer.
70mm is *not* stocked in Holland AFAIK, neither is 4x5".
Foto Objektief Vak in Groningen has the best prices on HIE in 
Holland, so they seem a good source for ordering. Above f250 exBTW no 
shipping cost either (guess how many HIE 135/36 a f12,50 I ordered?....;-)).
