Film over 11x14 in size is difficult to maintain tight contact uniformly
across the paper with a contact printing frame especially when using films
with thinner substrates.

Regardless of the size prints made using a vacuum easel will be sharper.
With some processes and papers this may be difficult to perceive unless
prints made in each type of printing frame/vacuum easel are made side by
side. Since you mentioned that you want to do plt/pld printing a vacuum
easel will aid in achieving sharper appearing prints.

Vacuum easels also are quicker and less tiresome to load, especially in a
long day of printing.

BTW, I've made several 12 tube UV printers and the DIY path will save you
substantial bucks but does require tools, and a moderate degree of
mechanical and electrical aptitude.
