There were a few good links on the Megatokyo forums of old - I'll see if I can scrounge them up...

Okay, here's one shop that might sell a few ABe doujins: http://www.alohaanime.com/ . That is, if they're not sold out, and if I don't get to them first, and if I can ever get their broken webpage working to see which ones they're selling (it was pretty much the whole Haibane set, plus a few others, as I remember from gazing at it wistfully when I had no means of purchase).

Hard to tell what they have when their images aren't there...

I'm hoping to run across some of ABe's work at SakuraCon this year.

Yeah. Emailed them about that. Got an out-of-the-office-till-next-week message. Anyhow, I don't recall them having any amazingly rare items - just the (original, not script collection) Haibane series and maybe some other things like Not Found.

Is it even worth hoping that ABe stuff might be up for grabs at Otakon?

Okay. Update on what's available from them (different from last time, they're now sure of what's in stock). They have multiple copies of the three story-centric Haibane doujins (no Lifestyle Diary), Not Found, and White Rain. They've also got one copy of their tarame paradise doujin, too, if anyone wants that. Sadly, no Ryuu Tai - that one's out of stock now.

bagels - if you request the hen da ne guys (ttp://www.hendane.com/) they can probably get some for you. Most larger doujin shops have at least a few ABe doujins around, and I think (from talking to them a little bit) these guys know what they're doing.

there's also a tiny chance that I'll be at otakon with ABe doujins to sell.

FYI, if Aloha Anime still has the doujinshi in stock, I can vouch for their quality. I purchased the reprint edition of "White Rain", as well as originals of "The Haibane of Old Home", "The Haibane of Old Home vol. 2", and "The Haibane of Old Home Extra Edition". They are all in superb condition.
