A version of this bench could be built at low cost by a beginning woodworker with a very basic set of tools in a weekend or two. Mike Siemsen and Bob Rozaieski have really shown the way here. This is important because the initial learning curve is very steep and you really need a nice bench. Think about what it would have meant if you had had a bench like this when you were starting out. If you did, I think you were prescient. I wasn't.
Of course, you can easily make a more challenging version of the bench. If I had it to do over again, I think I would use the dovetail joinery for the stretchers and notches in the front aprons from the original. Just a nice historical connection.
