For me it depends on the complexity of the technology. Some javascript controls library where I only need a few parts of what they do? No thanks, I'll look elsewhere or just program that myself. Something more complicated like a graphics engine however? Well I guess that's hard to price. It's going to depend on the use-case and your industry and turnover of your company. But I despise it because it means I'll get e-mails and phone calls from this company for the next six months. Once they even sent someone to a stand at a tradeshow my company did despite me saying that it was just too expensive to consider. I wish people would advertise a license based on the client's turnover - <1m, <10m could have stated prices and >=10m could be "contact us". But I totally understand why companies don't want to do that.
