First time I've ever seen one, and it'es for sale, dirt cheap too:
Fender "Prototype" Alex Gregory 7 String Stratocaster - eBay (item 260593644302 end time Nov-24-10 03:02:29 PST)
Looks interesting though, if they'd put a humbucker on the bridge and offer more colors
and a sane price I think alot of people could be interested.
i know it's a petty distraction, but 3 dots to show you that this last fret is the 24th fret? in case you didn't know that your last fret is THE 24th fret? otherwise a perfectly stunning looking strat. w/o those dots, the guitar would've kept all of the traditional lines of a strat, sneaking in the extra frets and string....
