F-100 is very inexpensive at around $200 for good ones. I have 3 of them. You can find them on APUG classified from time to time at around this price. You can also find them on most used places but you'd pay much higher.
"Quality" of the image has to do with lens, not the body. If you mean 35-70mm f/2.8, then you'd be able to use it with F100 as well.
