You are right, rebar is quite inexpensive.  It can be purchased in (usually) 
20ft lengths at most lumberyards.  It is sold in sizes from #3 on up, the 
size corresponding to 1/8" diameter.  Thus, #3 rebar is 3/8" diameter.  You 
probably won't find the stainless laying around anywhere, though.  It's used 
in special situations where corrosion resistance is a major issue.  Much 
more commonly used, especially in bridges abd other structures, is the green 
epoxy-coated bar.  It is, in turn, tied together with epoxy-coated wire.  
Most housing foundations and driveways will be using regular uncoated 
mild-steel rebar.  Scrap should be easy to find anywhere a house foundation 
or driveway is going in.

Another possible alternative, if you want the stainless, is a steel 
distributor.  A friend of mine works for one here in Denver.  I got some 
stainless tubing and rod from their scrap bin for nothing to use for JL 
electrodes and such.  I forget, has anyone used stainless rod in a spark 
gap?
