To me the clear winner of business would be the site that has available pricing for base + options. Literally they can make an easy $2-$4k sale just by adding [Buy now] button, considering that the rest of the pack are playing tough sh.. to get with the prospects.

I also found one site that has "add to card to reveal pricing" - which is perfectly fine with me. The problem with that specific site is that they only carrying outdated models.

PS: this is hardware device, not SaaS or service.
