the Jerker is legit. I hadn't seen it before. It's a shame these are both hard to find. As affordable as they are, I'm sure IKEA's margins are still really wide on products like this.
I'm one of the founders of http://www.RealScout.com, and we're building software that lets you search by wants like house faces east, within 0.25 miles of a Google shuttle stop, open floor plans, remodeled kitchens, and hundreds of other criteria.
We get much of our data from sources other than the MLS, so it's far more accurate than some of the descriptions from listing agents that national search portals query. We also have search pages (http://www.realscout.com/categories) that allow you to view all the photos of the features you're searching for. In other words, you can see all the backyards of Palo Alto listings on one page.
Our software is still in beta, but we're rolling out new functionality daily.
