Ok, as someone who really wants new sideart (and can't afford much now)..
1) How did you have it printed?
2) On what?
3) By who?
4) How much?
and it looks GREAT!
Bleh, that last post was just supposed to be a "Modify", sorry. I hate having
spelling errors.

To answer your questions:
1) Kinkos (believe it or not)
2) The marquee is their "back lit" material. The side art is their "ready to apply graphics".
3) See 1)

4) The side art was expensive, almost $180 for both sides, the marquee was around $22 bucks.
They had to send the stuff off-site since only a few Kinkos sites do this kind of work.
I'm happy with it. Last time I went to Kinkos and had a marquee done it looked awful but
they didn't do it the way I mentioned above.
Thanks for the complements!
