Specifically a portable folding bench. I have seen them run from $200ish down to $120 locally but for $45 I could just get a folding table (the heavier plastic ones) and chair at Wally world. Anyone gone the cheap route and found it worked fine or would it be better to plump for the proper bench? Opinions? Experiences? This would be for use at a pretty spartan range (Alabama Swamps range) with somewhat uneven ground at the shooting areas.
