Pitts will do a few more than the RV and a lot will depend on the exact version, but certainly OK for things like tail slides and inverted spins, as for cost, yes the S1 is cheap, as are many single seaters, because most people like to be able to take a mate up, not so sure you will find a two holer so cheap!
Pitts is not that practical for Xcountry, not so economical and limited in bag space. rv is much better here.
Difficult to land? Just a case of proper training and does not really need that much runway - depends what you compare it with!
