Ken,
Do you currently have a dust collector of some sort? A planer begs to be connected to a dust collector so that will also be a cost.
That said, I heard today that Steel City will be including a dust collector with their planer. I saw one today at Woodcraft and it was priced at $450, but you can get some discounts now and again and if it comes with a small one machine collector it may be worth it.
I don't know anything about this planer, but Steel City sure seems to be getting good reviews across the board.
Probably worth a look.
