Ok, I've reached that dreaded moment when collecting grinds to a halt. I've got a complete uk run of the original comics, (though some are not as mint as id like),+ Action force crossovers and collected issues, but I'm missing 27 of the final 32 issues. Is it worth paying the big money for these issues on eBay, or is there a better way? Currently, they are around £6-8 each, some as high as £20 for the very late ones. Should I just give up on a complete collection? Do these issues turn up in auctions??
