I built one, and later saw a simpler one. Very fast, very simple. I think my total cost was a few cents.
Google TDR DIY pulser. One from an old magazine (Jim Williams) looks pretty good, using collector breakdown of a 2N2369. The one I made used one IC and a few resistors.

How does it work.
When I was working with microwave semis it was either a tunnel diode or a Step Recovery Diode.
