To help avoid confusion, I would point out that these enlargers are now branded as Omega/LPL (not the former Saunders/LPL) in the USA, and they are not the same enlarger as the enlarger branded in the USA as Omega/LPL 670 (or the former Saunders/LPL 670).
Speaking from the perspective of past confusion.
Hope you find one Todd.
Your other option is to try and find the Universal Glass Carrier for the 6700 and then you're covered for all formats supported by the enlarger. They're getting a bit difficult to track down new since LPL no longer manufactures them, but they do pop up used every once in a while.
Out of stock at KHB, but this is what it looks like:
Interesting, I did not know that the folks at the VCP used eBay. I'm a geezer and have never used eBay.
I paid a visit to the VCP earlier today (I belong to a print sharing group that meets in their space) and took a look in the thrift shop (which I try to avoid if possible as I do not need any more 'stuff'!!!!). They had two bins full of negative carriers of all sorts. They clearly have much more stock than what is listed on eBay.
Willoughby, the thrift shop manager, said to contact her with the specifics of your needs and they would look through the pile to see if they have what you need.
