A deer stand does very little to keep the deer from smelling you, it gives you a better vantage point and it keeps you from being eye level with the deer. I hunt from the ground with a rifle and have had alot of success.
I dont necessarily think you have to have a scent lok suit to successfully mask your scent. A shower and good cover scent have always worked for me, and to be mindful of the wind.
Buy the stand and some no-scent soap, maybe some earth scent waffers, youll be good to go.
