My first UV printer was very simple.  I took a four lamp fluorescent strip 
lamp and screwed 3/4 inch thick pieces of plywood on the short ends.  These 
acted as "legs"   The pieces were as high as the fxiture sides plus ~ 4.5 
inches The unit sat on a couter top- with the tubes facing down- the legs 
held the unit so the tubes were three inches above the couter top.  I put 350 
bl tubes in it.  The four lamp fixture was just wide enough to expose an 8 
inch wide strip.  I was able to make 8 x10 with this.

What's the biggest print you would want to make with one of these?  Do you 
want to be able to expose more than one print at a time?

I found that 4 ft UV tubes were cheapest locally.
