Web App to Monitor Items in Multiple Auctions

[TwinLakesPark]

Does anyone know of an application on the web that allows you to monitor items in multiple auction houses?

I am having a hard time keeping track of all the live auctions (i.e., SCP, MEARS, Goldin, Grey Flannel, etc.) and the items that I am interested in. It would be great if there was a single web application that I could log into and view all of the items from all the auctions that I am interested in, as well as alert me to new auction items and notify me of items in my "alert" list. Think of how ebay works with your saved searches, and emails you a list every day that meets the requirements.

Somebody please make my day and tell me this exists?
