So good... so cheap... can't comprehend...
Seriously, I love your Krashrak the Stalker for Inquisitor (might've been good to put "Inquisitor" and "NR" (meaning no reserve) in the title?) and your Kyran the Hunter is just awesome.
I'm looking for these to go up!! This will also be a good experiment, with the (suuuuper low) starting price. This is how I do all of my auctions (7-day) but I recently go a piece of advice here that I thought might be good for painted minis:
The poster said that an experienced ebayer had advised them, if something doesn't sell, put it up again and Raise the price. He said it's worked almost every time. Granted, he sells Really well painted models (like yours) so that is the difference- for me I'm selling for bargain prices, so getting more people interested in a good bargain makes sense. But for extremely well-painted work, I wonder if this would work better for you?
I'm thinking of these guys, the "Dragon Painting Service":

They sell for really high prices, but they always SET really high prices, and they've got the ball rolling that that's what people expect to pay for their work. They've also got auctions that go for 30 days, with only "Buy it Now" or "Make an offer" options (no place bid option). That might work really well for you, as if no one "Buys it Now" after 30 days, you could sell it to the person who made the highest offer.
Again I've never put up something like that, but it seems to work for them. I linked to their second page, but they also have a first page where their smaller auctions are. The 30-days ones are mostly for numerous squads, but you could try the same thing with 10-day, etc.
Just some thoughts

and I'll be watching these auctions end!
