flexwatt can be ordered from most places already wired. I just started using flexwatt and like it more for a few reasons. First, it gets the temps up higher so if my temps drop at night for whatever reason, it will stay up there. Second, they are much thinner than the zoo-med. Lastly, they are tons cheaper! You can get 11" foot length for like $3.50 plus a few dollars for wiring. Very simple to use and you choose how long it is.
