You can get a good stand for under $100, and right now is the time of year to get it. Most places will have them going on sale. I strongly recommend Dick's Sporting Goods if there's one near you. The one where I live has all their stands on sale. You can get a good climber stand for WELL under $100. I saw one the other day for only like $39. Most places have their 15' ladder stands on sale for around $89-$100 right now too- (that's what I use, I like them the best) Ladder stands take a little longer to set up, but they are more sturdy to me and I like the sturdiness! If you do go with a ladder stand, try it out in your yard a few times. Set it up, and take it down over and over again. After awhle, you'll get pretty fast w/them. The first one I ever did took me like 45 min to set up and get all ready by myself... now I can do it all in about 15 min.
Make sure you pick a good spot for your stand too. Find a good trail, food plot, or watering hole the deer like to use. I do this by using trail cameras. They do the research for me. Find a hot trail and set up a stand w/in range of it. Good Luck!
