fmark: Welcome and thanks for having interest in this side of the hobby. If you want to go purely crawling, almost all of the big brands have them. There's the Axial AX10, the new Axial XR10, Losi's Comp Crawler and Night Crawler, Kyosho's Rock Force, HPI's Crawler King, Venom's Creeper and rigs available through online shops. If you want to go scale, the Axial SCX10 is the most capable, commercially-available kit. Tamiya has the CR01, High Lift and the CC01. The yellow FJ40 on the recent video is actually a CC01. It's very capable as long as you modify it's suspension and steering geometry. Parts are available locally and the kit's price won't hurt your wallet. Hope this helps and hope to trail with you soon.
