I really like weaver reins and bridles. I have a Billy Cook bridle that I LOVE... this thing is years old and is used every time I ride... I need to replace a screw right now and a piece of leather is coming off that just needs to be glued down or something... no biggie.
I like Classic Equine boots and pads. Tacky too.
I really like wool and felt pads (no specific brand).
