I am in the same boat as you... I got soiled with the Sony and stuff like BookIt... now that I have the Kindle, well, I have to do without it.
LRFTools took me a couple days , no kidding, to get the hang of it. I used to to convert books to HMTL and then used Calibre to convert it to mobi.
If you are looking for something to convert BookIt pages then I think you are wasting your time
