So far I've been using the ABS glue that came with my FX kit, and it's working perfectly for me. I'm not in a super rush to get mine done, so I'll just glue something, clamp it, and let it sit and dry while to go to school or sleep or whatever. I usually let everything dry for about 10 hours at a time. As for the warping, I'm not going to argue with anyone, but I have yet to encounter this. I used a pretty generous amount on my hand plates to keep the elastic bands secured, and I haven't had any problems yet. Right now I've only glued my arms (hands, forearms, biceps) so I'm definitly not an expert by any means, but this has been my experiance so far.
