Best way to do pricing research for industrial equipment?

Conjoint can work but sample size is the killer with niche B2B — you'll struggle to get enough respondents for reliable part-worths. Honestly, for heavy machinery I'd lean toward in-depth interviews combined with a competitive price ladder exercise (show them 3-5 price points and ask where they'd switch suppliers). If you do go conjoint, keep attributes to 4-5 max and consider a simplified menu-based version rather than full CBC.
