It depends on what you want to do with the car. If you're going to tow, you're going to need different springs to "normal". If you're going on corrugations, you'll need shocks that have a good (or really good) heat dissipation rate.
If you're willing to do it yourself, ask Zordo on this forum for advice and a quote. He will NOT send you up the garden path.
If you want someone else to do it, look at your requirements and see if any of those come within budget.
Personally I was looking at Sax springs until they started having some major troubles. I'm not sure they're over their issues, but their triple action springs certainly LOOK good. Eventually I went with a total solution from ARB - Old Man Emu Nitrocharger Sports shocks for their high heat dissipation rate, and dual-rate Dakar springs for the rear (HD coils up front). Performance is superb.
