I've been using my Epson V700 for 4X5 and my V500 for 35mm and medium format so I don't need this unit I purchased from Betterscanning.com earlier this year. It's in great shape since I've hardly used it. It includes the T-locks and one ANR (anti-newton ring) glass insert. The dual format holder plus the t-locks sell for $89.95 and the glass insert sells for $29.95, I'll sell both for $65 which includes shipping in the U.S. Paypal and U.S. Postal money order accepted. PM me for an international shipping charge.
