Pulsin

[skimask]

got it! i'll get a crystal as soon as i can to get pulsin to work. thanks again skimask.

The only problem with going with a faster oscillator and using pulsin is that you might end up counting too fast and max out the pulsin statement before you actually finish counting.
If you've got an idea of the maximum pulse width that you'd ever be sampling, you should base your oscillator choice on that.
Once you've got that down and working, there are other ways to count pulse widths, using a timer, a capture, and so on...
