I've been looking for a good battery mod for a reasonable price. I kinda decided on a Chuck mainly because of the enthusiasm of all the Chuck owners. I bought a 905 because it seemed cheap...and it is. I sent Jeff at Thagbuilt.com a message from his contact page about a week ago and have not gotten a response. I also thought that the nautilus sounded good (and it uses the 14500batts I already have) but I've sent Bill (Shrek) messages from three different places (one site, another site and an e-mail add. listed in the text from one site) with no response. Dosen't anyone want to sell their product? Do a brutha gotta beg?
