Agreed, and probably a better idea than the alternative starters, they're shouldn't be any issues starting our little motors when they are operating as they should.
I'd then spend the money on as big a battery as possible for more (CCA) Cranking Amps, and improve all related cables, grounds and connections to as big as practical!
For example, the bls race 33, almost a 2.0l high compression motor manages to start from a rather pitiful sized race battery, but its quality connections and cables ensure that every critical single volt and amp makes it to the starter and ignition circuit, and voila!
