Luminary manyshot merc armour budget recommendations.

Right now I'm using a redeemers armour with chance to gain frenzy on hit with crafted fire resist. It's working really well so far, but the only other better options I've seen so far is the grasping mail lighting overcap crit mod, and that thing is very expensive. I'm wondering if anyone has figured out a really good merc armour that's between 10 to 20 divs in cost, or is the frenzy mod a good target.
