est nullum problema tantum

I think your numbers for starter garb are about right. Starter rapier armor should start, I would thing not being a tailor, a bit higher. I would guess around $100. The not very garb like Zen Warrior fencing tunic is $50 alone. Add their $25 hood and their 25 pants and your at $100 for something bearly passable. So starting at $100 for the begining fencer would be about right.
