Baron....
Not sure if you have considered this but meat bombing worked for me for the first 800 hours or so, then went on to IREX/CIR/ATPL/Barons, Bongo's, DHC6 etc etc......
A sense of humor is required for sure and the money is **** to non existent but the flying is great fun and loads of hours, depending on where you end up.
Retractable not an issue, but you definitely need to get one going forward, so bite the bullet there as soon as finances allow.
Enjoy the journey......and STAY SAFE
