If I wanted to upgrade what should I realistically expect to get out of my current units which are a Gen 1 Helix 10 and Gen 2 Helix 9 Chirp. Both with SI/DI, orginial equipment, original boxes, etc. Is $1000 feasibke? To high? To low? Trying to get an idea so I can plan out the budget ahead of time for the next units.
