If you can only have 1 stand, assuming you have trees in your area suitable to climb, I would start with a climber. This would allow you to hunt more than one location and would be the easiest to move around. As time goes by, you could buy some hang on stands to put up in places and leave for the season.

Personally, I use a climber and about 6 hang on stands. Another use I have found for a climber is using it to put up my hang on stands.
