I've recently been playing with both my Folks old 640 (TIP film) and an old 210 (fuji film) and I really prefer the Fuji film/210 results and the pack film is cheaper ($8-11 us vs $23 for the TIP film) However, as you said, the pack cameras are definitely more involved. My biggest issue was learning how to pull that paper tab out without tearing it (I messed up two packs of film before I learned how to do it.) One thing, if you get the camera from FilmPhotographyProject.com it will work right out of the box where as you can't be 100% sure with ebay...I bought a 360 and need to do a battery conversion...nothing wrong with the seller, he was honest and sent that which he advertised (FFP converts the batteries where applicable before they sell the cameras.)
