Can't tell you a reasonable price in NZ, since it depends on supply & 
demand, but here are some pros & cons:

Pros:

Usually available cheap.  Simple, 3-500Z's still available.  Lots of 
useful modifications available.

Cons:

Getting old, power supply components and blower may be aging.  GOOD 
3-500Z's can be hard to find.  Does not cover 160 meters.  Slow 
open-frame t/r relay.  Build quality depends on original builder.  Lots 
of inappropriate modifications available.
