Specifically, this: http://www.amazon.com/gp/aw/d/B0030T1BRE?pc_redir=1408764475&robot_redir=1 It's really just molded legs to simplify 2x4 construction of a workbench. Of course making a workbench using legs made of 2x4 or 4x4 is really easy. Workbench construction is not rocket science. But the kit linked to is well reviewed, and I suppose makes things simpler and faster. I may re-build my workbench to be longer than 8', and for whatever reason that product specifies up to 8'. Regardless, I'm sure longer lumber would fit in the kit, or be easy to build from scratch. So, anyone have experience with kits like this? Any pros or cons? I can build either way, just wanted other opinions. Thanks!
