Congrats on the licence.
No reason not to move on to a C172 or the Pup, either of those should take around an hour to check out on - though there is no guarantee as it does depend on your ability, I would be very surprised if it took you as many as 6!
As far as airfields go it is a good idea to try for one with a hard runway if you want to fly much in the winter, though, unless you buy your own it may be a case of where the aircraft type you want can be found and convenience for getting there, the easier it is to get there the more you will fly.
Pup150 is a lovely aircraft to fly, not sure of maintainance costs if you buy though, nice for the basic Aeros, and if you do not turn it upside down it is still nicer to fly than a Cessna or Piper, though really only a 2+2 rather than a full 4 seater.
