Blaze, in my opinion, at youre defence level, you'd better off working towards getting pernix, yes it degrades, but the money that you can make in the 10 hours it takes to degrade to a broken counterpart would definatally make up for the cost of the repair. Especially if you have 99 smithing and use an armor stand, the price that's needed is nearly halved, and it works with assists as well!
But all this being said, if you still don't want to buy a degrading armor, then just get the Armadyl set, its pricy, but well worth it. Its classified as power armor, so it does take a little reduction in the Armor Rating, but it also provides a damage boost. With the damage boost, you can kill things quicker, making it well worth the money spent on it. I use it whenever I need it, and it helps a ton. I'm 84 ranged, and 95 defence, so I'm well about your level. I don't use extreme potions either, so if you have those (or overloads) then you're in luck because you can do a heck-ton more damage/second than I could right now.
Good luck with choosing your armor set!
