Hi Justin,
We get these types of requests frequently here, so there are many recent thread with advice for an initial laser purchase. I would highly suggest reading a few of those threads, but the bottom line usually ends up being safety advice to protect yourself and others as well as specific recommendations for companies / lasers that are of higher quality.
Both of the units you linked are very cheap entry level lasers and likely to be a disappointment, although we don't know you specifically want to do with it (graphics, beams, ILDA show playback, etc.). It would also be useful if you added your location to your profile so people can point you to the best vendors / people in your area.
