I've sent a handful of messages to Betterscanning over the last few month to no response. Time for me to move on and find another solution. With the highest quality scan I can get out my V700 being the goal: what's the next best negative carrier I can buy for fluid mounting? Should I buy the stock Epson item? I shoot mostly 4x5 and some medium-format. If it's relevant, I shoot almost exclusively Portra 160 and HP5. Currently I'm dry scanning with the stock, glassless Epson 4x5 carrier and using a carrier from Lomography for the medium format negatives. Thank you all for your help.
