Sorry. I asked the budget then forgot to post back here. Anyway, looks like you’ve had plenty of feedback since.
You seem to have found what you are looking for too.
I did the search for a fat bike thing this time last year (including joining the really helpful UK fat bike site).
Although I wanted something very different. Old school/ traditional / adventure (or whatever you’d call it) geometry. So ended up with my Pug.
I’d recommend a decent tyre pressure gauge too as playing around with tyre pressures and seeing what works for you is part of the fun.
All the best with the new purchase when it happens. Enjoy.
