I purchased mine through SECO, and after 5 years, I will break even in the cost.
Some prefer to pay the $6/month.
Their unit comes with an outlet measuring device in addition to several surge protectors for one's home.
I feel better when I know it's done right. Some people are handy and can save money.
Some things in life aren't worth, skimping on. IMHO
BTW - Another thing about moving to TV, is to keep your checkbook, handy. I feel your pain and I have been here, for awhile.
