I actually prefer to buy firm-priced pins. I don't feel like haggling. Too stressful and makes me feel like a cheap douche. So I go and I look the pin over. If I feel it's a fair price, I hand over the cash. If I don't, I walk. No BS. Both times I bought a machine on firm pricing, I may have paid a few hundred too much. But in retrospect, I'd do it again because they were both turned out to be great machines and worth every penny.
