If it's for a long-term installation, one with more room than you think you need is worth the extra weight and expense. The last two I bought, both of which I've given over to my son, were Rivers Edge models with rails. Even the wide one-man model will allow you to rest your rifle beside you on the seat, with the barrel resting on the rail. On a long sit, that makes a huge difference in your comfort and also lets you use your bino, rangefinder, camera, etc with both hands. Cheap stands are usually sturdy, but often have crappy seats and don't have the sound-dampening washers, padded rails, etc that good ones have. It makes a difference. Be sure to get a good locking cable to thwart casual thievery.
Whatever you decide on, better get hoppin', as supplies go fast. Check Amazon and Sportsman's Guide for pricing.
