Photomatix Pro is a great piece of software and it is what I currently use to process my HDRs. I talk a lot about it here in my Photomatix Review. It is also mentioned extensively in my free HDR Tutorial.
You can buy Photomatix Pro from the HDRsoft website. I think it’s only about $99 and you save 15% off with the Photomatix Coupon Code of TREYRATCLIFF.
I also get asked a lot “Why not just use HDR Photoshop?” My answer is simply that Photomatix Pro does a much better job of creating a high-quality HDR image.
