Hueco Tanks guidebooks?

I'm trying to find the Matt Wilder guidebook to HT online, and it's out of stock everywhere (except Amazon, where it's running ~$250). Is it out of print or something?

Assuming that I can't get my hands on it, does anyone have any other recommendations? Obviously I'm using this site, and huecotanks.com has some good guides, but it's nice to have something detailed to bring with me. I'll probably try to find the Sherman book too.

Thanks!

I was just down in Hueco and the guys at the Rock Ranch told me it's out of print because an updated version is coming out later this year. Every gear shop down there is sold out too, so don't plan on picking one up when you get to Hueco -- I made that mistake. Good luck.

Aahh, okay. That's what I was afraid of. Thanks for the heads up!

If you need a guide book before the new one comes out John Sherman's second edition guide is a little out dated but will do just fine its the only guide I use when I go to Hueco currently....12$ on ebay...
