I've used these in the past a few times for projector installations where running a factory made VGA cable was not workable.
They work great and are quite small and the receiver has the short cable on it so no need for an extra VGA cable.
Just make sure you use sheilded CAT5e/CAT6 cable.
From memory they were around $200 and come as a pair.
I got mine from SnapperNet but they don't seem to have them on their site any more.

CDL distribute a good range of extenders http://www.cdlnz.com/index.html?do=VMC100&code=VMC100

The extenders will usually come as a pair, a sender and a reciever.

Give them a call and they should be able to point you to a local reseller or send me a PM and I can help you out.

How far do you have to go?

I have just finished installing my projector using 15pin VGA connectors soldered on to standard Cat5e UTP. I couldn't find STP cable from a local supplier and really wasn't expecting great results, but thought if I at least pulled the UTP through the wall I could use it to pull the STP when I got some.

Had estimated the length needed at 10m, so I got about 15m of cable and did a test run with the cable still all bunched up - not so good, quite a bit of ghosting but other than the ghosting the picture was suprisingly clear at 1280x720 60hz which gave me hope.

Once the cable was in the wall & across the roof space it turned out to be closer to 8m. I choped the cable & re-soldered the projector end connector - time for a test:
Sorted! Still a very clear picture, good colour and ghosting all but gone! If I switch back & forth between a short factory VGA cable & mine I can see a slight difference. There is one barely noticable ghost, but at viewing distance (4m) from a 80" screen it looks good.

Cost: 2 female vga connectors & cable ~ $12. Worth a crack I figured!
