Best website builder for makers, sellers and doers.

Hi Henry, Glad you found the piece helpful! Good question. I'm not 100% sure which builder would be better for the kind of site you have in mind. I'd recommend using the free trials available to experiment first. Wix has a very useful guide on creating a one-page site here: Hope this helps.
I agree with you that Pulse CMS offers an interesting way to go, without databases. Before moving all my sites to WP over the past two years, I had always felt reluctant to use databases: but testing WP had convinced me to go ahead. Although I do not use it at this point (I played a little bit with previous versions), I bought a Pulse CMS license, if only in order to support that interesting project. I do not rule out using it for a site some day, at least experimentally.
