[Equip] eBay Hitron CODA of Comcast?

I seen a Hitron CODA-45 on eBay for only $39.99 I know there's a retail version of the Hitron CODA-46 that's sold for use with Comcast. The Coda 46 has a switchable diplex filter, the CODA 45 is fixed for mid-split. The approved devices just say "Hitron CODA" nothing more detailed, so I put in an offer and picked one up for $30 on eBay, we'll see whether it actually works on Comcast when I get it.
