Actually, the frequency used in Contact was 4.45 GHz, or hydrogen times pi.
This frequency is just above the satellite TV C-band allocation, and has
indeed been used for SETI (most notably by Dr. Blair at Parkes, Australia).
But there are indeed some interesting frequencies in X-band as well.
There is a radio astronomy allocation at 10.6 GHz, and I seem to recall
Malcolm Mallette published an article last year about doing SETI in that
segment. Malcolm, if you're monitoring the list, do you care to comment?

The cheapest I've seen so far is $500, by an accomplished scrounger. The
most expensive I'm aware of is $20k. I think $2k is about average, but
remember that this technology is getting more affordable all the time.
