I had my Pronto TSU-1000 from Phillips kind of die on me so I went ahead and bought the TSU-2000, and now I have the old one just laying around. The screen just seemed to not be accepting the correct location of the taps on it. it acted like it was not calibrated, and when I did calibrate it it would just do the same thing. I think that a 1ft. drop caused the problem. Anyway, if you are interested in it (and are one of those people who like to play around with this stuff) how does $50 sound? Email me if interested. (sorry about the lack of price originally, It is my mistake, and I honestly just wondered if anyone would even want it.
