Buy what sounds best to you, and is best suited to your specific needs. Everyone has their own axe to grind on the forum, but I think the best judge of what you need is YOU!
BTW: I performed with a band a few weeks ago, a country band, one that really rocked the house. They loved what they heard from the PSR-3000 and asked when I could join them again. Not a prayer--and not enough money.
Good Luck on whatever keyboard you decide upon,
Gary
