I'd also suggest MR Cad but would strongly recommend that you haggle for the best price.
You'll choke when you see his enlarger prices.....
I'll second les as they are so rare on ebay. I have one from Mr Cad and it is a 20x24 vacuum model in great (newish) condition. It was £450 (Fair price). Larger ones are no more expensive as they are less desireable due to size. HAGGLE and be aware that his prices vary quite wildly as does his descriptions of condition. He will deliver for a reasonable price, but you may have to wait until his delivery van is going to your vicinity (He's in Croydon and he delivered to Bedford for about £10-15)
A 20x24 will give you some comfort space to mount 16x12 with 4" borders (plenty IMHO).
I would very strongly advise you NOT to go for a pressure based mount that is smaller than the mountboard size. I know you can clamp it in several areas until the whole mat is covered, but this is a pain and often leaves pressure marks.
My vacuum press is fast and does a perfect job, every time. My clamp type one was a huge time consuming pain.
A very worthwhile investment for 100% flat prints. I only wish mine was twice as big (for now I mount 20x16/20x24 prints to 2 ply 20x24 board to keep them flat and then use conservation tape to make pockets to hold these in the right place in the window mount sandwich, so a bigger press is not essential right now. I just dont know what I will do with the 40" FB prints I'm planning to make...
Happy hunting!
