Anyone know of any that are good and preferably free?

Windows or Mac?

Windows

Depends on what you're trying to do. On Windows the only real free choices are Windows Movie Maker and http://www.lightworksbeta.com/ (the first being limited but simple, the second being full-featured, but like any full-featured one it's got a steep learning curve)

If you just want to edit/splice/compress game video/FRAPS pieces together, many will work. If you want to get a bit more complex or are talking about video camera footage or something a bit more professional, it can go in other directions.

For FRAPS type stuff I still use http://virtualdub.org/ (windows) You can do some other things with it as well, with filters, AVIsynth, and some knowledge of the program. But it's a lot of work if you want to do more than edit/splice together (no easy "timeline") and it doesn't come with many codecs (you have to supply those).

If you want fancier stuff, or for other types of video, then yeah, try Lightworks.

i really just want to edit some fraps stuff, so i'll check out this virtualdub, thanks for helping.

It does have a little bit of a learning curve even for fraps stuff, but nothing major. The site has some help documentation but if you have any questions, feel free to ask or PM me.

Note it's best/smoothest to work on the raw footage. So if working on multiple files, save the pieces as "Direct Stream Copy", then load/append the pieces together to compress/save the whole.
