I found an Acurite Weather Center 02032CAUDI at Costco for $99, which seemed like a pretty good deal.
It includes the "colour" display panel and a 5-in-1 remote sensor that includes temperature, wind-speed and direction, humidity and rain gauge.
The colour in the diplay is really just a fancy background sticker with the usual calculator-style liquid-crystal display in front. It does seem that for whatever reason the viewing angle is extremely limited; even off centre a little and it becomes very dim. It has an inbuilt backlight that is quite bright; it is either off or on (3-levels) or in "auto" mode, which dims it to the lowest level at certain hours. Hacking in a proximity sensor might be a fun project. The UI is OK; it shows indoor and outdoor temperature/humidity, wind-speed/rain and with is able to show you highs and lows with a bit of scrolling.
I was mostly interested in its USB output features. After a bit of fiddling I can confirm I've got it connected up to Meteobridge that is running on a Dlink DIR-505 and reporting to Weather Underground. One caveat is that you do need to plug the weather-station into a powered USB hub, rather than directly into the DIR-505; I believe because the DIR-505 can only talk directly to USB2.0 devices and not older 1.5 devices like the weather station. Another small issue is that the Meteobridge license is €65 which is not insignificant. Of course with some effort you can roll-your-own such as described in this series which is fun if you're looking for a project.
Luckily I had a mounting place that backed onto my small server cupboard, so I could easily run the cables through the wall to power and the DIR-505. Without this the cables might end up a bit of a mess. Combined with the fairly limited viewing angle afforded, finding somewhere practical to put the indoor unit might be one of the hardest problems.
Mounting the outdoor unit was fine, but mine is a little close to the roof-line so I'm not sure the wind-speed and direction are as accurate as if it were completely free-standing (I think official directions for wind-speed are something like free-standing 10m in the air). It needs to face north; both for the wind-direction and so the included solar-panel that draws air into the temp/humidity sensor is running as much as possible (it works without this, but it's more accurate with the fan). One thing is that it needs to mounted fairly level for the rain-gauge; it includes a small bubble-level on the top to confirm this. Firstly you'll probably find that most mount points you thought were straight actually aren't! Since the bubble is on the top, if you want to actually see it you need to be above it (obviously) which may not be possible if you're standing on a ladder and mounting it over your head. This may be a situation that inspires a very legitimate use of a selfie-stick.
It's a fun little device and fairly hackable for an overall reasonable price; I recommend.
