Open houses both broker and to the public can work and you can pickup some buyers along the way.

Ratjer than doing an open house, try to focus on advertising...much of it can be done for free...its amazing how effective craigslist has been. Be careful with how many listings you get on there....if you put too many, you will make a bad name for yourself.

Placing a listing on the MLS is just a formality to me.  While I welcome broker cooperation, I would love nothing better than to locate the buyer directly.  Two things I don't do: open house and print ads.  We all have our niches and tricks that work for us...this is mine.  Since only about 25% of my listings typically allow signs, I focus on internet marketing and direct mail.  Pay-per-click has been very effective for me in capturing direct buyers.  When sending direct mail pieces, I can't stress how important it is to have a quality print provider.  Cheap, thoughtless postcards won't properly reflect how you want your market to perceive you.  In actuality, the mail pieces are marketing prospective sellers...give them something to remember you by.

And most importantly, make sure your listing is priced properly (see my other post...market's been trying to suck me in, but with great advice I'm still resisting).  If not, you're just throwing good money out the window.

Like Susan, I am doing less and less media advertising but I still mail to the neighborhood. What I emphasize is the available Visual Tour. I include it in all of my mailings as well as with a sign rider. I use one URL for all my domains and they can select the one they want to view once they are on the site. Pick something easy to remember in case the drive-by's don't have something to write with. Mine hits them with the same verbiage twice to help log it into their memory:

"Tour the Interior at www.TourInterior.com"

You could set up an interior page on your site with thumbnails of all your tours and point the URL to that particular page. Keep the URL short for advertising purposes, though.
