Just to update my bucket buying experience.
So thanks to responses here I now better understand micro vs mini bucket profiling and that lead me to discount Rhinox because I couldn't see any evidence (online at least) that they profile buckets for micro machines differently to those of mini machines, although I'm open to correction here.
I called Digbits for a quote, unfortunately while helpful with advice I couldn't get any discount on the prices shown online. They wouldn't even throw in a set of pins. At this point we were discussing a £500+ (ex Vat) order so I was a little surprised there was zero movement and tbh if they would have thrown in a set of pins (quoted at £24) I may have placed the order on the phone there and then. Even name dropping
@Gunners didn't appear to help
I then called Strickland as they received a few votes in this thread and I've now order a 12" and a 24" bucket from them.
Compared to Digbits, Strickland were ~£50 cheaper (£349 vs £300) and they were happy to throw in a set of pins for free.
I tell ya, there'll be some muck shifting done in Kent in the next 2 -3 business days.
