My best advice is to pick up a stand from Wayne McLeod. I have one of his scope stands and am very pleased with it. It is sufficiently heavy to dampen vibration and movement on windy days. It is purpose-built for across-the-course shooting.
Wayne makes a great product and is a great guy.
It does hit the upper price limit, but it is worth it. I have a Freeland's stand. It is a good product. I bought Wayne's stand to replace it several years ago. I'm no longer looking for a stand and only keep the Freeland's as a backup.
