Where to get a good 80% 1911/P38 Frame

Hey
Thinking about the next project and Im thinking about a 1911 or a P38 from a 80% frame. Leaning toward 1911 for a .22 conversion[:D] and availability of parts but could deal with a P38. Anyone have experience with any of this or know any good places to go for the frame? Ive seen the tannery shop and DIYguns has a 60% 1911 frame for a good price but dont want to get myself in too deep as far as the work goes but want a nice in-depth project. Thanks
