Looking for opinions on what one should expect to pay for a PSA Graded Gretzky Rookie.

I am not looking at anything under a PSA 3, and nothing better than a PSA 6. What's a realistic price point on these cards?

My preference... buying something in that low-mid range for grades.... is to find something with decent centering, and no creasing (so I'm expecting softer corners, probably not amazing edges).

Posting here, rather than "want to buy" in the the buy / sell forum - because I'm more wanting to just do my homework right now and figure out what I should be expecting to pay before I start trying to make offers, but if you've got one that meets the description of what I'm asking for and want to move it, I'd be happy to hear what you're asking for.
