Default Fill me in on HRV's, what to look for, how to hook up

My house has been getting tighter and is now starting to get to the point of feeling stale in the middle of winter with the windows closed for weeks on end. So I'm thinking of getting/building an HRV. I was following the build it yourself thread since most were $800-$1000 but recently ran across a commercial unit available here for only $380 and I see one online here for $500.
Home Hardware - AIR EXCHANGER, SYMPHONY 1
Home Hardware - AIR EXCHANGER, HV1.5

What I have no idea is what values mean something useful when it comes to efficiency. Also how do I install these things? My house has central air with ducts running to every room. Can I pull air out via the return lines and return fresh into the feed trunk or do I have to add vents to every room I want air going into/out of?
