I got tired of swapping the base heater from one sizer to the other and ordered a new one from Magma. The rep that I talked to on the phone was very friendly and knowledgeable. He stated that they were out of the heater elements and expected a shipment about the first of April. A few days ago my new base heater arrived!
Its a quality piece of equipment! The base is thicker than my Midway heater. It has an indicator light on the heater housing and has a pretty substantial looking cord with a nice inline switch. I bolted it down and used it last night. The instructions stated that the heater control was pre-adjusted for a given type of lube and I didn't have to move it.
All in all I'm really happy with this purchase.
