KEH also stands behind their equipment with a very good return policy.

Edit... I just checked KEH, they have a 120 BGN back for $21. Not a bad deal at all.
Thanks Paul. What I'm looking for is an ETRC 120 film holder/insert. The ETRS has a detachable back with a film holder/insert akin to a Hasselblad. That is Dad's problem. He has the ETRC which does not have a detachable back and he just needs a 120 film holder/insert to replace the 220 film holder/insert he already has. I don't believe the 120 film holder/insert from an ETRS back will work in the ETRC. I did not see any ETRC related equipment on the KEH website; however, maybe I just need help finding it.
