I'm at gencon currently. So I'm typing this from my phone and can't do the web trawl nessissary to provide specific model numbers and links.
But I would be highly surprised if you can't get a normal router (for less than the $75 being asked for the device you linked), stick an open source firmware on it*, and configure it to operate in bridge mode.
You should be able together something more versital, for cheaper, and with more ports.
I'm sure someone with more time and better Internet access than me can give you specifics
* this step may not even be nessissary depending on the brand.
