I have a Nest carbon fiber, no longer available. Pretty nice. The grease is very stiff. Sort of a love hate thing. In cold weather a real problem. I did replace the grease for the pan motion but left the stiff grease for the tilt function.
I also have a Lensmaster RH-2 that is hand made by a guy in England. Easy to disassemble and clean. I like it a lot. Comes with one 50mm Arca plate and one 140mm Arca plate. Cost is £187.95. That works out to $263 US. I got mine delivered to me in the states in a week.
Built like a tank. Weighs in at 1.19Kg or 2 pounds 10 ounces. Advertised for 45 Kg (100 pounds) static load.
