if you can swing the pistolpacking.com bandito rig, go with that. it costs a little more than the others but is well worth it. i have tryed uncle mike's and a generic cordura case, i didnt like it at all. noisey when you draw and attracts and holds moisture in the fabric.
slings are another nice option, but if your carrying a treestand on your back, they tend to bounce off one another- not good.
I am a cheapskate and I use a drill holster (harbor freight $3.99). I had a picture of this on the site but I can't find it at the moment.
good luck

i have heard quite a few talk of this but havent tryed it myself. for $4 , a guy aint risking much if he doesnt like it.
