So, Hashaton: is it worth buying the precon and upgrading for him (the second commander) or should I just build a Hashaton deck from scratch? (budget)

Title. I love esper, I love zombies, and I love cycling so this is already one of my favorite cards printed. Is it worth buying the precon to use him as the face with upgrades, or will there be too many to make it worth it? Looking to spend ~$100 but could do more if there are any particular heaters

It would be the $50 precon plus ~$50 worth of upgrades if I went that way
