Willy,
If you go and fly a taildragger with your instructor for (say) five hours you'll pay the going rate for the aircraft and his time.
If you go on a 'conversion course' which typically lasts five hours or so you pay (wait for it)........... the going rate for the aircraft and instructor.
Tain't no different. It's only a name.
PS No Instructor is going to let you go solo after 'a circuit or two'.
