Cheers Ishtar, and yep, I'm doing the same with my HXD-710, which is a great machine, even with all the little quirks and foibles we've been talking about here.
The equivalent new Pannys do have HDMI, an SD card slot, video upscaling and dual layer DVD recording for a similar price to the HXD-710, as well as a built-in VHS deck - which is the bit that interests me.
That's mainly because of picture and sound quality - my Sony VHS has a standard (non-RGB) SCART so picture quality suffers when passing between the two machines. The Panny - being an integrated unit - is specifically designed to convert VHS to digital at best possible quality. Since the original VHS image is already so rubbish, it'd be good not to lose any more than you have to.
But you're right. There's nothing wrong with the HXD-710 I've already got, and yes it's daft to start hankering to replace it again only a year later. There's always going to be something new and tempting around the corner... thanks for your reply.
