| Cemspec, as Nelly suggested buy a reputable brand of heat mat and thermostat. I have had friends run cheap heat mats with no thermostat only to have them stop working after 6 months and ended up buying a good one anyway. A good thermostat and good heat mat should last you many years. If you have spent 4 or 5 hundred odd dollars on a pair nice blonde macs then then its worth spending the 150 dollars on some top gear. Keep in mind once you have the gear you can use it again in their next enclosure when they out grow their click clacks. |
