Shrink Wrapping

With Art-Whirl happening tonight at 5pm, I have been thinking of a way to shrink wrap my prints from MCAD.  I am discovering that it is an expensive process. I could take it to Kelly's Gallery in Woodbury where the owner Don Kelly quoted be at $26 for each piece to be shrink wrapped. He said he would cut me a deal if I brought in 10 at a time, but honestly I was wondering if I could do this cheaper by myself.

I found a few sites for materials:
Acid-Free Foam Board    $148.30 for 25 sheets
Shrink Wrap Film   $64.00 for 28" x 500' roll

Of course this doesn't include the tools I will need:
film sealer
silicone pad
film dispenser
heat gun

Or I can just get a kit like these:
Dick Blick Kit      $228.99
