I love Nunn Finer: the reins I have are of unbelievable quality (and can't beat the price), their breastplates are very nice too.
As for boots, Mt Horse worked the best for me.
I also like Woof brand a lot (I have boots and protective vest).
MT Toulouse is a nice brand as well (have a saddle, and all my stirrup leathers are by them).
Thinline: for pads (hated the reins though)
Back on Track: tack works wonder
