1) Wireless 2.4ghz camera system - $45 via Amazon marketplace - this is a step up from the 900mhz of the old setup, but it might interfere with the Wifi in the house...it also has nightvision....sweet...
2) 22" LCD HDTV - $115 via NewEgg - not content to go with a 6" or 7" screen, we're now rolling on 22" in HD. We are going to be able to see the individual hairs on his head. I love the Viewsonic products - they are relatively cheap, well made, cool designs, although sometimes lacking in the contrast ratio....
So for about $20 less than the going rate for baby-specific video monitors ($160 versus $180) I now have a multi-use setup that can grow with more kids. When Willameana comes in a few years I can just add another camera and we can watch both of them. Will post pics of everything once it's up and running.
Update - everything is hooked up, had some interference from the wireless network, but a bigger antenna solved the issue. Here's the final product - or BabyVision as Sue calls it:
