I'm a little biased and completely impartial, but I've been doing a lot of VFE/ASP work as of late and I've gotta say, it works very well and has been relatively easy. I'm doing a session on this at our upcoming VFE DevCon.
As far as Visual MaxFrame and WestWind goes, have any of you that mentioned this actually tried this? I don't think Drew himself would claim they work together. Virtually all of MaxFrame's functionality is form centric.
