I also use Loadrunner, but I am not a Mercury Certified / Trained individual. I've used it for about a year, and I've also got WebLoad from Radview (cheaper, does a lot of the same stuff). Of the two I definitely prefer Loadrunner. It seems that Mercury's product is more polished and has better tech support backing it up. If money was not an issue I would choose Loadrunner, but yes, the virtual users for it are pricey.
