Well UmaroIV's Combat Hacker is darn good, though it doesn't utilize anything that wouldn't be permissible in missions. I'd take a look at it if I were you. Of course, I'd also note that I typically prefer adapting UmaroIV's Mercenary Rigger to hacking focus than using the Combat Hacker, but that's a personal preference, as they are both very good, IMHO.
As for alternative stuff, if your GM allows you to use pirated software rules and/or you are considering using Activesofts in-game, then you might consider Move-By-Wire 2 instead of the usual Wired Reflexes 2 and Reflex Enhancers 2. Assuming you want all the benefits it grants you (including the bonus Dodge ranks), you're basically trading 6 BP (1 in nyuen cost, 5 for Restricted Gear) to save 1.5 essence.
Move-By-Wire (Rating 2) 3 Ess / 85K nyuen and Restricted Gear = Reflex Enhancers (Rating 2), Reflex Recorder-Dodge (Rating 2 - which technically doesn't even exist), Skillwires (Rating 4), Wired Reflexes (Rating 2) 4.5 Ess / 80K nyuen.
Make it Move-By-Wire (Rating 2, Second-Hand) and, assuming you want all the benefits it grants (including the bonus Dodge ranks), it actually costs less in terms of both creation BP and character Essence then buying all the parts separately (and of course there is no rating 2 reflex recorder).
