Sounds to me almost like you're trying to read the speed of a mouse wheel encoder...or something along those lines. There's methods of doing that, and hardware to do that for you. I can't place any off the top of my head... Maybe somebody else knows...
close, i am trying to do an encoder and motor/gearing from a printer, but i do have a wheel from a mouse just in case the printer one doesnt work (the encoder has a LOT of interupt bars, if more than 255 of them, i cant use it... i will store the last location in the eeprom (so when i turn on/off, i will still know where i was when i left off), and of course eeprom only goes to 255. i kinda want to stay away from "off the shelf" units since they are kinda costly, and i have a fair amount of spare PIC's laying around to tinker with. it there is something i might be able to hack out of (lots of spare crap!), might do that.

thank you for the fast response!!
