I don't know about cheap but I bought the cheapest I could find at the time: http://www.ebay.com/itm/320735055777

So far it's worked well for me. Haven't tried anything highly detailed though but I don't see why it wouldn't work.

I develop it with washing soda, which is much cheaper than the stuff they want to sell to you.

I use laser-printed artwork on a transparency sheet and expose with UV LEDs through a sheet of glass. Darken the toner with a whiteboard marker as suggested here.


Of course, they may have changed their stock since I bought from them.
