Personally, it would be great if they packaged up a conversion kit of a system board and instructions to upgrade your TI to a TI 2
I'd go for that ....
I'm also a tech so I'm comfortable ripping into equipment ... Other music shops which have a service depot could aid in the execution or installation for the user ...
just my 2 cents ... support may open up a can of worms though , as some people may tackle it and fail which could be $$$$ ... so they would have to have an idiots guide for installation.
