Hey man, if you're considering collecting vintage then I'd suggest buying a couple large lots on E-bay. I did the same thing when I started to rebuild my personal collection.....I bought two larger auctions ($300-$500 range) and I got a ton of vehicles, and 3 cases of figures that all had weapons and were mint. These collections were bought from the original owners.....not a dealer.....so I had a pretty decent idea of what to expect.
Bargains can be had on E-bay for vintage stuff all the time.......just be patient when searching for auctions.....and if you find one you like...but the price is jumping on it then bail........there will soon be another auction that will please you......patience is the key
Oh, and owning Ewoks ain't so bad
