Dealing with FSBOs

Dow Jones’ MarketWatch recently published 6 tips for those planning on selling without a real estate agent. Aside from the basics, (staging it properly, having the proper support lined up, etc.) they gave the following advice:

[ask] at least three agents for a free comparative market analysis before setting an asking price — as long as you’re prepared to hear their pitches on why you should enlist their help to sell the home

This struck me as a little unscrupulous, especially if you have no desire of working with any of them. Leading people on in any circumstance is unfair.

How would you deal with this situation?
