Chris at Wolfe Ridge is a good guy to deal with. His base model splitter doesn't have a hydraulically adjustable wedge, but it's an available option. Also, he offers different sizes of cylinders and pump and engine combos too. I've never run a timber wolf, but at $9k I'd never be able to afford one even of I wanted one.
Personally, I'm super happy not having a stand alone splitter. Thanks to seeing Sawyer Rob's awesome TW3, I bought a Wolfe Ridge version of the same thing. I love that the height is adjustable, and I love that the motor is 12' from me. Unfortunately, that means that i can't comment on the ergonomics of his standalone machines. Anyway, I'm glad that you checked them out blackdog. Happy shopping, and enjoy your new splitter whatever you choose. Oh, and be sure to post some pictures when you get it!
