Ultratherm UTH pads from Reptile Basics are very good. As Pitontheprowl said use foil tape and you can re-use the pad when/if you change cages. Heat tape is fine but if you don't want to wire it just get a UTH. If you are looking to save some cash a decent thermostat for around $31 is the Hydrofarm. It works well with UTH set ups. There are lots of options. Good luck.
