Welcome from Gainesville!
If you're looking for a net on the cheap, and are not DIY capable (if you are, I highly suggest checking out the various designs in the DIY forum here), it may be worth looking into a cheapo head net from your local Army/Navy surplus store (most sell the Coghlan's brand), worn with a baseball cap or visor to keep it off of your face while you sleep. Won't do as much for your body (so, come summer, you'll want to invest in a full-sized net for down here), but it'll keep your neck and face from being eaten. They run ~$5 to ~$10.
Just a thought...
