Even just a ballpark is helpful. As an industrial engineer, I deal with this all the time - I don't have time to go to lunch with you and talk about one of 300 components on my machine, but is your fancy gizmo worth it? When the tech specs are public PDFs, that's great, when they're locked behind an account creation email flow to spam me later, that sucks (and you'll get a company disposable email), when the account doesn't get created until your sales rep looks at my company website to estimate how much money you can take us for, it's too late; I've already designed in something else. And what's the price difference between the standard and deluxe models? Is it 20%, or a factor of 3? If your product is moderately compelling but has public pricing, you're in the running, if I have to wait for a quote you'd better be really compelling.
I might be one of those long tail customers for SkyFi, my Dad's birthday is coming up and I think he'd love a print of a satellite photo of his cottage on the lake up north...it needs to be better than Google Maps, but I'd never make it through a manual sales pipeline.
