Honestly, the decker/rigger hybrid works better after character creation.
The sheer cost of a cyberdeck is such that you're probably not going to upgrade. Ever. You're going to get the best deck you can at character creation and guard it with your life, using your money to either get helpful 'ware or take up new hobbies. Which, counterintuitively, makes one of the more expensive archetypes one with more spare money than the rest.
From a decker at character creation, they could use their money to fan out into the wonderful world of rigging after.
Alternately, technomancers have even less use for money, both during and after character creation. You can go with low-priority magic bought up with special points from your metatype, take higher-priority resources, get a low-end control rig implanted with a low-end RCC, get your drones, rig the old fashioned way, then for skills, focus your resonance skills solely on matrix perception and sprite use, and let the sprites do all the matrix heavy lifting, freeing up the rest of your skill points for rigger stuff.
