I have an opportunity to buy a 2006 TN75A for a reasonable price. Did NH make any changes to the TN75A that would make it a better unit to own? Or, do you know of any problems that were isolated to the 2006 year model?
Don't know for TN, but if new T series are sucessor, that means that you have offered one from last series of that model. Last series are usually the best, as all bugs are sorted out. I will go for it (if is in good shape).
