This sounds like a better idea than buying a 4-5 year supply of blades that you haven't tried. I would compare the SE Derbys with some of the DE blades like Feathers, Merkurs, Swedish Gillettes, even the Derby DEs.

Unless cost is a major concern I would also consider a Feather AC. I much prefer it to a shavette type razor like the Ustra.

Hopefully, after you try a disposable blade straight you will try a regular straight. If you do so, make sure that you have it honed by an expert first. I think you would find it to be an improvement over any other method of shaving.
