I've debated new but I'm trying to keep my wheel budget tight and I've seen a lot of inexpensive wheels (comparable to oem take-offs) but I always worry about durability when it comes to cheap wheels. I had a 97 Mustang years ago that I was building as a track/drift car and I went cheap on the wheels, I tapped a curb doing a tight right hand turn and had a wheel damn near shatter so I've been wary of cheap wheels ever since. At 3 tons minus all the car seats and other gear the Suburban is a heavy girl and I don't want to risk hitting a rock I didn't see or something and repeating my exploding wheel incident while I'm out in the boonies with an angry wife and four kids.
the Fuel brand wheels and the pro comp I referenced are made for 4X4's mostly, they are a popular brand of the cheaper variety but are pretty solid none the less.
I have the fuel wheels on the my Silverado that I have taken off-road a number of times and have complete trust in them
wheels have load ratings just like tires do, most of the Fuel wheels I see have a 2500lbs load rating X4 is 10,000lbs more than sufficient for a suv
at any rate I was just sharing that there are options out there other than oem for a reasonable price and decant quality if you are unable to find oem at a acceptable price
every once in a while you see some take-offs for a good price but they are gone pretty quickly, you have to be prepared to jump on it with cash in hand, in my case usually those kinds of deals are out of town and no chance of getting there before a local snaps them up
