I use a Leupold Sequoia 20-60X80mm Angled spotting scope. I bought it in the kit form and it cost just under $600.00 about a year ago. The kit comes with a hard case, tri-pod, and detachable lens shade. Pretty nice set up, however, the tri-pod is just a step above the bare minimum in mount quality.
Also check out the Leupold Golden Ring 12-40X60mm HD spotting scopes. The glass is a bit better in these than the Sequoia sereis they make. These are also available in a kit form and are around $900.00. In these kits they have two extra goodies than the Sequoia kits. They have a vehicle window mount for the scope and an adaptor for mounting a digital camera to it.
I've noticed that most tripods that come in these kits are about the same quality, no matter who makes them.
My brother is a photographer nut and turned me on to some of the tripods he uses. They use what they call a "liquid mount" which makes traverse and tilting of the scope/camera smooth as glass. Super nice! These can be had for around $200.00 and up from any high end camera store.
