Have you checked out the mega bumper thread? http://www.wranglerforum.com/f33/meg...ad-134959.html
I went with a Poison Spyder brawler lite. There stuff is highly respected, and trail tested. There welds and construction are really nice. You could find something cheaper that would get the job done. If you shop around you will find places with free shipping.
A number of bumpers are going to require you to relocate your vac pump (2012+ issue). Mine did not, though it wouldn't be that huge of a deal to do it.
I bent the stock bumper going through a rather deep ditch at 45 degrees. That was one reason I went with a stubby. I also like the look better, like that it is lighter, and there should be no issues with larger tires when turning.
Stubby bumpers are illegal in some states. Im not sure if its going to get you pulled over, but maybe something to consider.
Full width bumpers that hug the fenders don't look as good if you decide to go with flat fenders down the road.
You need front recovery points. Even if your getting a winch. It will help if you use a snatch block in that case, or if it breaks for some reason. A good number of tube style bumpers don't have hooks or D-ring locations.
The bar that comes up to protect the grill is called a bull-bar. If it tilts forward a bit the bumper would be referred to as a "prerunner" style. If it goes up to a point, it's called a stinger. A stinger is used to prevent forward roll overs and protect the radiator in case of a side rollover. I have heard that stingers can make some engine work (oil changes) more challenging. I would assume it would make tight trails a pain.
My bumper came shipped bare steel. I had it powder coated (with zinc primer) for $170. JCR in addition to PS also ships bare. You should test fit before powder coating or spray painting. Bare has advantages of being able to choose a color or finish you want. It also is less likely to chip in shipping. It added a week before a could install mine.
Some bumpers are more winch friendly than others. Some bumpers will put the winch on top and others will have it sunk lower. The on top will likely be a stronger bumper construction. That may not be a huge deal. Much like the wind blocked to the radiator on a top mount would be of little consequence. I personally would not want a super hidden winch that would be hard to spool or use.
The stock bumper has plastic screws that are not going to screw out. Start a metal screw into them, and pull them out with pliers. Don't forget to wear safety glasses because of dirt. I have a swivel head ratchet that will work at an angle. I highly would recommend getting one for the install. Here is an example.
