If you would, would you also figure out for us what the cost, roughly of making this change would be to a customer of your store, rather than an employee?

Let's say I, as a perhaps elderly arranger home player, walked into your store with a T3 under my arm (OK, I'm too old to lift it, assume a grandkid is carrying it!) and wanted to walk out with a T4... What kind of a price are you going to quote me?

And then factor that real-world figure (not the figure you are going to have to pay yourself) into whether the improvements between the two represent value for money...

Every model is ALWAYS going to be an improvement. But that improvement is going to come at a cost. When faced with paying full retail, and getting a perhaps not too generous trade in (I remind you, pretend I'm an elderly arranger player with no eBay chops and the usual willingness to pay whatever you ask ), is the difference between the two a good decision for most of us who DON'T get gear at cost or thereabouts (and can't sell our trade-ins for top dollar)?

If that weren't a consideration, of course ANY model change is 'worth it', but factor it in and perhaps it can color your decision...
