Even the archetypes, which are far from optimized, start out with customized commlinks (specifically the drone rigger, hacker, and smuggler).
Note that while Availability may restrict you to rating: 5 hardware to start out, you can still get utilities at 6 - they will only run at an effective rating of 5, but when you upgrade your hardware, you won't have to get a lot of new utilities, too. One thing I would consider would be using the restricted gear quality to start out with a Response of 6, which would let you have System, Firewall, and utilities at 6.
