I agree with all the others, however, I prefer to use the Progressive unit that is attached to the pedestal. There is a way to chain it there and easy to read. Just plug it in to the electrical plug, and there is no problem. I worry if something goes wrong it could sacrifice itself and cause a fire or burnout. When not in use, it's in my storage unit. It's over $300 and worth every penny. Try tweetys.com and choose to hardwire it, or plug it into the pedestal. At Tweetys, the portable unit I prefer is $363.88 with no tax or shipping charges I believe. The model # is EMS-PT50C Manufacturer: Progressive Industries
Built in Lock Bracket: Allows the user to secure to power source to prevent theft
