My asnwer would be try before you buy..

Go to your local dealer and see if he has got a Krog on display.. if so, sit down and play with it for a whole day.. I even know a dealer where i buy regularly that allowed me to take a demo model home for a few days to try it out and see if i liked it...

But then i realise that not everyone has some of the greatest music stores in a 60 miles range from where they live..
