I have used Summit climbers before, and found them comfortable and the cable system easy to adjust.
I have also used Ol Man climbers, and liked how they folded flat for easy carry. The mesh seat was comfortable.
I also own a Timbertall that I bought when stationed in NJ. Very light.
As for accessories, make sure you have a rope or reel to bring up your equipment; a good body harness in case you fall or the stand cuts out on you; and an equipment hook (or hooks) to hang things like binos, rangefinder, rattling horns, camelback, etc.
