This is a great deal.
I've been looking at upgrading from my old HTM MX-500 (love it but the LCD screen went dead many moons ago
).
Anyway, I've just about settled on the Harmony 670. The cheapest I could find it new is ~$125. Refurbs you can find ~$70.
$80 for a new one is a steal... Too bad I don't have the money to pull the trigger on this deal!
Good luck.
