Also Larry take into condsideration how many thousands you made with these units. Yes great investment!

But Donny, you always seem to assume that the REASON you made all that money IS your current arranger... Truth is, you probably would have made just as much money with your previous arranger (after all, as you keep pointing out, it's the PLAYER, not the tool that makes the difference, eh?).

Once you realize that, the cost of upgrading actually DOES factor in...

You invest in a Tool....you use that tool to work...you make money from your investment. After the initial investment is satisfied the rest is Gravy..simple as that.
If a year after that and thousands of dollars later in jobs you threw out or sold the TOOL you will always be ahead of the game & never lose a dime the initial investment.
