Has anyone used the TF20 or TF10 Tempering Machines?

Hi everyone! I am looking into buying either a smaller tempering machine like the TF20 or TF10 ChocolateTempering Machine or a chocolate melter and tempering myself. I have been looking into buying a chocolate melter from Mol d'Art and came across the TF10 and TF20 on this site http://www.tcfsales.com/shopexd.asp?id=86 However, I haven't ever heard of them and can't find any online reviews. So, I was hoping that someone can help me out and let me know what they would recommend.

Thanks!

Anne
