I own the API grand slam supreme and love it Great stand. The summit Viper Xls is good too. My friend uses one we both do a lot of bowhunting.
The Best new stand that I have seen though is the new Buckshot stand. It is by far the lightest while still being large enough to accomadate hunters in excess of 200lbs.
Just make sure you spend the extra $20 for the larger sized stand which ever you choose you will appreciate the extra room.
