Always wanted one of those Digilog case too but rarely see it on eBay these days.
Don't get this incessant need to keep on buying Aluminum Cases for Realforce Keyboards?
First off, the RF is the very best thorpie, made for the public. Their case is firm and stable so why the need to throw it away for some dodgey-arse aluminum case, made by nobody's?
Just stay with the original keyboard because it still is better than any aluminum case, plus you'll save hundreds which can go for another future RF keyboard purchase.
