min. HP for Zrun?

Hey peeps,

Wanted to know if a level 50 Sin and/or Fighter wanted to buy a Zhelm:
1- How much HP would you need to survive?
2- What level do you think you could purchase it without having to use HP equip and survive the run? If you used HP equips or pots? What sort and how many of them (for the pots)?

Thanks all for your answers.
