Hi, I just want to give an update. I decided to go with BK-5. Originally I want to go with EA-7, especially I got a great price from Hammer (I really appreciate it).

However, I am new to this "modern and advanced" arranger world (since my last keyboards were Korg i30s and E-36), and I felt intimidated by EA-7 sophisticated features. I was just afraid those features would be wasted as I wouldn't know how to utilize them.

So, this BK-5 would be my first modern keyboard, perhaps I would upgrade to higher end one in the future.

I got the BK-5 from eBay at a great price, I think he (72af9z4) is in this forum too. It's is new, unopened box.

Thank you everybody!
