Thanks for the compliment. Luckily, there's lots of green vegetation in Hawaii for the IR at stand out.
First, I considered buying a converted camera on ebay, but I wasn't too keen on paying $250 or so for a camera that I would use occasionally. Next, I bought a couple of IR filters, and wasn't satisfied with them - the exposure times were too long for hand-held photos with the darker filters. Then, I found Kolari Vision, who would convert your camera for a nominal fee. Better yet, if you had a model that they hadn't converted, they would do it for $49, which fit right in with my pocketbook.
Of course, it will take IR color shots too, but I bought it mainly for B&W. It just takes a little brightness/contrast correction in Photoshop for the IR effect to stand out.
