To be honest, the SW barrel will serve you perfectly well if you don't plan on shooting 10,000 rounds per year.
I would however advise that you consider resale value, and the cost of barrel replacement in the future if you get more serious about shooting a lot. That extra $75 now will pay for itself several times over in the long run.
I would keep my eyes peeled on gunbroker for an HK94 barrel that someone pulled off a HK94 to install an MP5 barrel. Some good deals can be had if you are patient.
Best of luck with the project.
