Any tips for brands, models etc that I should keep my eye out for
If you're putting a child seat on it, it's difficult to go wrong with a 90s-onward rigid frame mountain bike. The added frame stiffness and longer wheelbase makes the bike a lot more stable when the child seat is on. They do come in large sizes, but they're not so common and you might have to look for a while until one comes up. Your budget will be easy peasy for a nice frame, set of strong wheels and an ex higher-end set of gears like 10-speed SRAM X0.
I'll look into this. Used to ride mountain bikes when I was a kid in the 90s. I'll dig out my old copies of MBUK and see what Kona's and DMRs were cool back then.

Don't forget to ask in the large frames thread!
