E Resources plus 10 starting Karma gives you 26,000 Nuyen, enough for the essentials, so don't completely discount it. It frees up more points for Edge and/or skills, while you will probably get plenty of money for gear once you have gone on some runs.
D resources gives you enough to get things beyond basic gear - a chameleon suit, a Maglock passkey, a flyspy drone, a Force: 4 qi focus, and so on. Plus, getting elf at C will give you an Edge of 4.
C resources, I would only recommend if you are getting augmentations. This choice costs you in Edge and/or skills, but it can be worth it, because some things are easier to improve with augmentations than with power points. That example I gave, used muscle toner: 3 and 2 reflex recorders, costs you a point of Magic, but gives you +3 to Agility and +1 to two different skills, which you would normally have to spend four power points to do.
