i did a search and most of the threads were from last year so i figured i'd make a new one. i have a 9500i and have been contemplating sending it in for the ~$130 upgrade to a 9500ix. from those that have done this, is it really worth the upgrade? meaning do you feel the price and time without it justified the upgrade? i'm on the fence cause i can't really find anything as of late saying it is of value to do it.
