You can check with KEX. He does ultra high res scanning using Imacon Flextight.
I've seen the scans, quality is excellent.:thumbsup: :thumbsup::thumbsup:
Can go to Fotohub. They are having a promotion for high res scans now. Check out www.fotohub.com for their address of various branches. They do a good job of slide printing and processing too, although they have since centralised their slide work at their Beach Rd branch.
