Simple test for anyone wanting to get into doing a transfer from 35mm, or who believes they know someone who would.
Buy one of the 35mm Star Wars or related trailers from ebay, (There are 350 35mm trailers on there right now) they crop up there all the time and don't sell for very much - a Star Trek Insurrection trailer is on there with a buy it now price of $5.
The trailer is guaranteed to be in far better shape than any SW print out there.
Get that transferred to HD and post back here with the results. Preferably pick up an older trailer like the gremlin's one for about $40 which will be closer in condition to a SW print.
If you can't get a 2 minute trailer transferred, then it doesn't bode well for getting 120 minutes done. If you can get it done then it will give you an idea of wether the quality of transfer is going to be worth it or not.
Buying a cheap trailer and trying to get it transferred is an almost no risk way to see if you could get a SW transfer done, and could be a lot of fun.
