I have a Carvin SH575. Fantastic playing and incredible midi capture, although a fair amount more than a Godin. The guitar is great even without the midi. I got it a long while back specifically for midi and at that time there were few other choices (Parker mostly), most more expensive than the 575 if you can imagine. Parkers run about 4K US.
Now, Godin and a few others (the Roland GK ready strat looks interesting

I also had a stick on GK3 pickup first. That worked fairly well. If your really interested Kristofer, I can send you the GK pickup I have for free. It's just collecting dust. It's this one....
http://www.sweetwater.com/store/detail/GK3The other thing is that they now sell GraphTech saddles and expander kit you can install. That whole system is probably close to $400 since you have to buy the Ghost saddles, Strat Saddles or Fixed Bridge type, and the Hexpander kit. Sweetwater.com has them when I just researched some. Of course, you have to do some body work to implant the 13pin saddle, but it essentially turns your guitar into a 575.
Edit : The You Rock guitar is as much as a GK3 pickup. The You Rock gets great reviews, but, if you're going to pay as much for the You Rock as for a GK3 I'd suggest you might look into at GK3 instead as it uses your guitar. Or, if your really interested, save a little longer and get the Saddles and Expander kit. The Ghost saddles do make a difference when comparing the capture quality compared to a GK3 pickup.
******Actually, I mispoke a bit. A GK3 guitar does need a converter unit of some nature........either an older Axon100, a Roland Gi20, a GR55.
Apologies to those mislead. But a GK3 is a more expensive option than a You Rock, albiet still cheaper than a GK equipped guitar as they also need some sort of converter unit.*******
