I believe 23 was the most recent update, and the Hughes is selling for around $300 on different shop sites, none on eBay that I've seen recently. I don't like it enough to pay $300, but it'll probably be the one to have knowing my luck and then I'll want it when it's a $1000 book...
No link because I'm lazy but bleeding cool has been keeping track, check there
$300 is WAY too much for a modern IMO. i'll be content getting the phantom variant graded and signed.
I have paid and might pay more than $300 for a modern, but the risk to me is that the book isn't out yet. Hughes + super hot female character + hardest variant to obtain could equal a huge gain for some people, but at $300 to me it's a high risk. If I really really liked the cover maybe, but I don't, I like a lot of the other variants more.
What if Hughes did a usual super sexy/risque cover for it like he has done in the past? His Supergirl and the legion 23 sells for well over $300, and quickly when they're listed.
