Forget tailwheel / aeros. Fun but useless when it comes to finding a job.
Wouldn't even bother with 200 series cessna time. Flying a 210 / 206 isn't exactly rocket science.
If all you want to do is invest some time rather than money , find a LAME who doesn't mind you helping out in the hangar and spend some time learning everything you can from Schedule 8 (and all other 999990 uses for hundred mile an hour tape). Oh, and don't forget to buy the LAME a carton as thanks for all the time you'll use what you learn in your first thousand hours or so.
Good luck
