Price comparison sites
I think that more than a few forum users could benefit from using a VPS price comparison site. These are six comparison sites that I know of:
https://www.vpsbenchmarks.com/best_vps
https://www.hostfind.co.uk/web-hosting/vps-hosting/
https://hostingsift.com/hosting?type=vps
I'm not affiliated with any of these. Feel free to suggest others.
The price comparison sites are all of varying quality, coverage and up to dateness. Nevertheless, I have found them useful, some more than others.
Obviously the best thing would be if the forum had its own price comparison section, kept up to date and containing all the offers posted. Linking products and providers back to their respective threads on the forum would offer a nice feedback loop.
I feel that in the end, price comparison sites do not only benefit the buyers, but also the providers. It gets the provider's name out there and gives the provider a chance to reach more buyers. Not everybody can be the cheapest, but each provider can be best in their niche. The filters on the price comparison sites are really useful to finding just the thing you are looking for. I think it's a win/win when the result is that the providers get the best customers for their service and the buyers can best fulfill their needs.
