(Limit the search to "only cards that I own at least 1 copy of".)
The website gives an estimated value of $241.40 (which I guess is about £125), but ultimately these things are only worth what someone is willing to pay for them. I also have 4 plastic Deck Boxes and 400 Deck Protectors (in a range of colours). Anyway, let me know if you'd like to make me an offer for any of these; I'd prefer to sell the whole shebang at once, mainly to avoid the hassle of a separate journey to sell one card at a time, but I'll consider any special requests.
* HP ScanJet 5200C (colour A4 scanner, supports USB and parallel). This works fine in Windows XP, but it's not compatible with Vista (as per statement on HP website). Looking on Ebay, a 5100C sold for 99p, and a 5300C went for £1, so I don't think it's worth trying to sell it, especially since I no longer have the original box. Basically, free to a good home, and if you feel inspired to buy me a Coke in return then I'm happy with that.
* LiteOn LTR-32132S CD burner (internal IDE drive - 32x write, 12x re-write, 40x read). I've now replaced this with a DVD burner (I was amazed to see that you can buy them for £20 now!), so I don't need it any more. It's not made any more, and I'm guessing that it's worth about £5. So, make me an offer if you're interested (even if your offer is "zero").
Edit: Scanner and CD burner now gone.
