Clean meaningful markup that works without js makes you far better than the median web author. It'd be nice if the images were also links, since the titles are pretty small Fitts' Law targets. Nobody is in the market for <i>everything</i> so I'd want to filter on price and maybe words like brands.<p>Have you considered how Craigslist reacted to PadMapper? So far they have not been happy or even coöperative about people building better alternatives to their UI. Good luck.
