Reading all these tripod threads got me thinking about how I need a tripod. I always seem to just rush my pictures and I don't get the results I want. So, what tripods/heads do you all recommend? I'm an amateur. I don't sell my pics for money. I currently have a D40, kit zooms and the 35 1.8 AF-S lens. Ideally I'd love to upgrade to a D90 or 300 (or whatever the equivalent is when I've saved up enough to afford one). I also don't expect to spend $20 and have a good tripod.
