I won my jumbo Combattler off of ebay from a Taiwan seller back in February of 2012. I was the only bidder at the starting price of $499 and no other bidders at the end. While not pristine, not a total beater either, it was a Shogun Warrior that was well played with and won many battles with some scuffs, scratches, and small body damage along the way.
For the rarity and otherwise much higher price for complete or better shape Combattlers, I think the price was pretty good. And since I had been making reproduction parts already and had some other fellow collectors that I could borrow parts to fix it up, I was able to take care of the broken, damaged, or missing pieces.
Several things that I did with Combattler:
