If I were you I'd set my sights on a C172 or maybe a Cherokee.
Older models of these can be found for not a whole lot more than a
nice C150 (do a lot of careful looking and jump on an opportunity)
and they will have a lot more capability.

Subcribe to tradeAPlane and start some serious looking. Be
patient and learn as much as you can about what's out there.
You can find a good running 172 that needs some upgrades and/or
cosmetic repair that you can do over time while you fly it.
If oyu are interested in IFR these models will be more viable
in the longer run than a 150.
