I have recently been in touch with Francis Shanahan, the creator of [tag]BaeBo[/tag] (uses many Web Services). He has revamped the UI, and I think it looks 10x better and is a much more useful Shopping mashup now. It is broken down into Shop, Browse, Research, Feeds.
It also seems to work fine on IE (except for hovering over the Pic which seems to constantly flicker). And it is all [tag].Net[/tag], which is great to see. Great work, keep it up! Read his blog entry or See the BaeBo site here.
