I was in a similar boat, couldn't decide to go for a Marantz DV9500 or wait for HD.
In the end I thought I'd compromise, I wanted a DVD player that outputs 720p for the new Sagem HD-D45 TV I have, so debated with myself on selling the excellent Pioneer DV668 for a player capable of outputting 720p.
The fact that the Sagem TV and Pioneer DV668 were incompatible over HDMI > DVI kinda forced the change on me too.
I went and bought the Marantz DV7600, and haven't looked back since, it is an awesome player with much of the performance of the DV9500, but at half the cost. If Blu Ray/HD-DVD were not being released soon I would have probably spent the extra on the DV9500.
If I were you, I would save a bit of cash and go for something like a Denon 2910 seeing that you seem to like the Denon brand or a Marantz DV7600. The money saved could go towards HD-DVD/Blu-Ray when they arrive, or even the Sky+ HD box when released in Feb
The money I saved over the DV9500 will certainly be put towards one of those options, most likely the Sky+ HD box when it is out. I may hold out until a universal player of some sort arrives that can play/record both HD-DVD and Blu-Ray.
Here's to the future and glorius pictures
