Thank you for posting your experience. It saved me. I too saw a TC5000 on craigs list sent an email inquiring about the equipment because I was skeptical because the price was 1/3 of what I had ever seen.
A few days later, I received a response directing me to a web site (http://www.affordabledepot.com) where I almost ordered the TC5000.
However, before making the purchase I tried to call their customer service number. Of course, I did not get a live person but a voice box. I then tried to find them on the BBB site as "Affordable Depot or MyOnline Depot" with no success.
I would just caution, "buyer beware".
