I've been putting my hang-on up and moving it when I find better places to hunt. They are a bit annoying to move from spot to spot, but they are worth it. I bought a hang-on from amazon and some climbing sticks there too. the stand was only like $33 and it comes with a full body harness. It's very sturdy, here's the link to it: http://www.amazon.com/Guide-Gear-Tree-Stand/dp/B0032X017O/ref=sr_1_1?ie=UTF8&qid=1348260704&sr=8-1&keywords=tree+stand
I weigh 251 lbs. and I feel like its pretty solid. I went to Lowes and bought a 7 ft 1/2 in. coated cable and a firearms lock. Cable only cost like $9. My stand shouldn't be coming off the tree unless they cut the tree down. Best bet though, get a climber from summit. The Viper SD is good. That's my next purchase. Plenty of pine trees and a few oaks, nothing to worry about though as long as you use the proper safety precautions i.e. tethering upper seat to lower climbing platform, putting in your fall arrest device, etc...
Happy hunting!
