Hi Dnj,
I was thinking to purchase the Roland VP-550 because of the vocoder and harmonizer. Now I am a bit confuse

What should I buy? What are the different between the two units? They are both not arranger. For the price of a use Discover5, it is cheaper than a brand new VP-550. In addtion, should I get the Roland E-50 or E-60? Does it have the same feature like the Discover 5 + the great arranger part. I am looking for your Roland expert's opinion. Thank you.
