Is anyone currently collecting these (or hoping to)? If so, what is a reasonable price to pay for these. I see a few singles and/or sets going on ebay now, and although I would like to collect the whole set (they're just so cool), I don't think I could afford it. I'd like to just get the yoda for my collection, but I don't know if I can bring myself to pay $15++ for a bottle cap! What are some of your opinions on these? Are you collecting them, and if so, are you using ebay? Thanks for any advice, God bless.
