Just start looking
I looked for around a year before buying. I read lots of adds and called lots of sellers. It’s part of the learning process. I’m in the Northeast, but flew commercially to look at one in Montana, North Carolina and in Texas. You can’t be afraid to travel to see them and if necessary, walk away. I did pre-buys on all of them and learned a ton. Given the cost of the plane, the travel was short money, well spent and fun.
If you are buying, it’s unlikely you will find the perfect plane. The perfect plane is the one you build for yourself. Have a list of priorities and compromises. Other than going from a trike to conventional or fastback to standard, you can change most other things as you see fit (at a cost). Discount your price commensurately.
Insisting on 200hp may limit your selection. You can change/modify the engine later if you want. It’s more important to get a well build airframe, in my opinion.
