These units are arguably the best Powerline adapters available in the fastest AV2000 protocol.
This is the best home networking solution imo unless you've run Cat 6 cabling around your house.
There appears to be low stock of AV2000 adapters including the TPlink model TL-PA9020P at the usual online stores, so to get these at a decent discount is a good result.
I called Good Guys to price match and they said the lowest they would go was $199.

And bonus, that price gets you two of them!!
