Anyone who is using a Letrilite UV exposure unit needs to keep an eye on eBay for the NuArc Mercury Exposure units. This is the unit that is sold by many of the photo-resist suppliers for faster, more accurate exposing of your film.
I bought mine new, about six years ago, for over $2,250. I picked up a second one on eBay for $325 last week. They seem to be popping up on a regular basis and selling very reasonably. Photobrasive has their new units listed for $2,500.
