This is just a table to stuff you with Amazon cookies. If you click any product, you get redirected to its Amazon page with the affiliate tag. Understandable attempt to make money but feels dishonest to me.
I'll make it more obvious there are Amazon links shortly; if I can make some towards the costs/time, great; but that's not the motivation, I started off compiling the table for my own use (I'm trying to decide on a CB) and thought it'd be useful to others.
I built a script that uses your timezone to guess if you're near the UK and forwards you accordingly (this was prior to this chart existing). I linked the CB chart to it to avoid reproducing the same functionality.
I can possibly do this in a different way, but since it doesn't cost you anything ending up on Amazon I didn't really think anyone would be upset by it. I just did what was easiest and most useful.
