Is $1300 a reasonable price for a used 13b?

Depends on the condition. Don't buy one at that price unless you can test it.
All sorts of bad things can be wrong.

Can you mount a starter on the engine?
If so get a compression tester and remove the schrader valve (tubeless tire valve).
Poke it in the lower spark plug hole and watch it as the engine turns over.
You should get at least 3 good pulses in a row of at least 50 psi or higher.
Front and rear rotor of course.
It might be possible to use a large drill motor or impact wrench with a socket on
the front e-shaft nut to turn the engine over at a fair speed.
Looking at the front of the engine it should turn over clockwise.

If no starter is possible listen for puffs from the exhaust as you turn
it over by hand with the plugs in it of course. One puff per e-shaft revolution
for each rotor. You can put your hand
over the exhaust port and feel the puffs. You can also feel the pressure
by placing your thumb over the lower spark plug hole.

There are some new cheap (>$200) bore scopes now a days that will fit
in the lower spark plug holes as well as the intake and exhaust ports.
That will allow some pictures of the rotor housing wear surface.

If it is locked up it could be total junk.
