Remember that HK has a new line of receivers coming out so the older models are going to start getting cleared out. There are some pretty good sales (30% off or more) happening up here (Canada), although HK prices start pretty high so I'm still on the fence.

You might want to just push for a good price on a 630, be a little patient and you might get it.
