I have a new set of Chicken Hawk standard warmers and a set of used Pole Position (3-way adjustable) warmers in great condition. PM me if you're interested. Price will be roughly the same for either set. Thanks.
Check out the MOTO-D PRO-Series Dual Temps in size 120/160......they get HOT and use only 750 watts per pair because they use Carbon Wire Heating. www.motodracing.com
I have the Moto-D warmers. I actually sold my woodcraft dual temps and bought the Moto-D single temps because of the lower wattage requirement. I have been very happy with them. I find with my generator the warm up is very good and consistent. I think the woodcraft were good but might have been closer to the limit of my generator and didn't heat as consistently. I have no affiliation with either, just happy with my purchase.
