Just wondering what the differences are, so I can decide if the extra money (seems to be around $35) is worth it. Also, will files/graphics created for the 3000 work on the 3500?
Thanks
Pros: TSU3500 has LED panel Light (the 3000 got dim after some years of use); The RF increased range and the learning got better;
Cons: Like in the 7000 series the hard buttons light don't go on automatic with the pane;
