If you take the time to hunt for good deals you can put a set together from used MB models on a budget. I found Brembo 4pot front and rears on eBay/for sale section here and hunted deals down on rotors. It's not as big an upgrade for an SRT as the limited but it's still an upgrade. If your willing to do a bit of work you should be able do it for ~1000. Waiting for/finding the good deals is the hardest part.
