I grabbed it from ebay... the total was cheaper. As far as I know, it's been accurate indoors as long as I stay within the infrared zone of 1 inch. The emissivity of water has not been a problem, though the model I have is not adjustable.
By default, it's set to 95E and water is at 0.95 (http://www.electro-optical.com/html/bb_ ... isivty.asp) which I suppose translates to the same thing. I'm not really knowledgeable on the subject, so I hope my findings are somewhat useful.
