Iceman, If you get one from Howie Glatter
http://www.skypointer.net/brktfr.html you can get a mounting bracket and switch so you can use it instead of a Telerad, may not save you much but it's one less item on your list!
Make sure you get one with a guaranteed 5mW output, some are much less (and less reliable), I think there is a review mentioning this on CN.
There's a recent thread in s.a.a. with a few links too.
If you really want to piss the astro-imagers off get one of these 40mW green lasers:
