I assume you're talking about your tie rod ends breaking, not your actual ball joints, right?
I'd just get a used stock steering stem, but then again, I don't roll over very often. If it's something you do a lot you may benefit from an aftermarket one.
First I would try to save the stock one though, I don't see why you couldn't bend it back with some heat and leverage. How in the world would you bend that though? I used a bent stock stem as a demolition hammer and it proved to be impressively stronger than a 1988 Nissan Pulsar, I can't imagine what you would have to do to bend that tab while it's mounted on the machine, it's gotta be 10 times as strong as the stock tie rod ends.
New rods and ends is a good investment. Take some advice from me though, it took me a couple tries and a bunch of wasted cash before I found anything worth my time and money. The best way to go is with a good set of stock style 12mm rods and ends. It'll be 3 times as strong as the stock ones and reliable. At all costs avoid anything branded Tusk, or anything from TrailTrackSand.com, same garbage. The Honda style rods and ends aren't worth it, standard 12mm ones are just as strong and cost less. You shouldn't have to spend more than $100 for a good set, I bought a set for my buddy's warrior a few months ago, American Star Racing (ASR) sells the 12mm kit on ebay for about $90 with free shipping. I have no complaints about the kit except the rods don't have a flat spot to hold them with a wrench, so you need to use something along the line of pliers or vice grips to hold them while you tighten the lock nuts. Years ago the 12mm kit I bought on eBay from a different seller had stainless rods instead of steel, and had flats on the rods so they could be held by a wrench. They were the same price and a little nicer, if you look hard enough you may be able to find them.
