Got a spare set -- well, I don't have a 5200 anymore, so that pretty much goes without saying. icon_smile.gif They're fairly hard to come by for the 4-port models tho (that's the one where the AC adapter plugs into the RF switchbox).
$20 (US) + shipping for anyone who's interested. Shipping will likely be somewhere around US $9 to the US due to the monster weight of that AC adapter.
PayPal only. (Need some digital cash flow)
