I would simply wait until you have an opportunity to PLAY a BK5 to make your decision. I don't know if you have noticed, but impartial opinion on this forum is about as rare as unicorn's blood!

Yamaha owners will tell you that you need to get a Yamaha, Korg users will tout their Korg's, and Roland users will tell you you need to get one of them. Not exactly going to help, is it?!

You might be better served fine-tuning your goals, and your needs. What KIND of music are you probably most likely to want to play? Each manufacturer seems to be a hair better at one style or another than the rest. TBH, I think this is THE most important question to ask.

The next thing might be to narrow down what the type of sounds you tend to use are. Are you primarily a pianist, an organist, a synth player or do you prefer horn emulation? Again, each manufacturer does each of these better or worse than the others.

Next might be, do you tend to use a very wide selection of styles, or were you happy with just a few really good ones? Again, different manufacturers, different results.

A bit more info goes a long way towards getting a lot less biased an answer, especially here!
