BSK, you've mentioned aircraft ranging from the Xair to a 172. They are worlds apart in terms of their ownership costs and performance/capability. Both are superbly good at doing what they are intended to do.
My advice would be to wait some more before buying as a sole owner, so that you can refine your plans for the type of flying you want to do.
For example:
Xair will be a disappointment if you want to go places any distance away and carry more than one passenger, but is great cheap fun flying
172 will be a disappointment if you want cheap flying from short farm strips and to keep the costs down, but is a very capable touring aircraft with four seats.
Renting and/or buying into a syndicate would allow you to get an idea of the sort of thing you will enjoy as an aircraft owner.
