Sirius unit from replacementradios.com?

[SurfToy]

Has anyone purchased the sirius add-on unit for the OEM HU from replacementradios.com? I tried a search and couldn't find any results. Looks like a pretty clean integrated solution, and comes with an ipod add-on unit that integrates ipod/iphone controls into the HU.

Toyota/Lexus/Scion - Toyota/Lexus/Scion 04+ Sirius Satellite radio +Aux/iPod: ISTY11 +SCC1

Thoughts? Reviews? Thanks.
