oh yeah. I imagine they're tough to find because of the brittle nature of the backpack pegs. Well that and they're really old and people lost them I think one of mine I remember hot gluing on because it broke.
And because it's so rare, FGB stuff is expensive! Sometimes it's just fairly expensive, but other times it's very expensive...that goes for buy it now deals, and also when starting bid prices and/or final bids on things...the best thing would be to find FGB at flea markets where people don't know what they have...but I've never had that kind of luck.
Galaxy Rangers are extremely rare. You'll hardly find anything, even in Europe where they where released and just to see 1 figure is a rare treat even if it's incomplete.
Right now I'm trying to get a few figures from a different line that you only see once in a blue moon if you are very lucky. I shouldn't be spending money anymore with the moving, but since these are so extremely rare, I have to make an exception, but I'm betting they will sell for far more than I'm able to afford :/
Filmation Ghostbusters figures are around, they were sold worldwide and you'll aways see a few on ebay even if they are incomplete. The vehicles, playsets and accessories are just very rare.
