I also have the Swaro 65mm spotter and I went with the Bogen Carbon Fiber 732CY. It's compact, light, plenty sturdy and it's around $199 (without a head). I put the 700RC2 head on it and love the setup! If you're going to be using your spotter standing a lot, this tripod might not be tall enough for you but for sitting, or if you're shorter, it's perfect.
Never used this tripod with a camera but you can also take a bag, like an empty crown royal bag, and carry that with you. When you get to where you want to set up, fill the bag with rocks and hang it from your tripod. This will help steady up your tripod.
