RE: 9303 or 10x
Since you are the only one with "your" dollar value system no one but you can answer the question and a side by side comparison of programing is only one aspect.
Since you seem to be 'feature prone' I'm guessing the 9303 will be your choice------I have a 10X and wouldn't go the other way-----but then that is 'my' value system.
When you make your comparison however make certain you also add in the cost of the 10X servos------if you do not and compare the 811 with the 8611a you are comparing apples and oranges.
