How much for this domain? It lacks keywords except bis can be used for business. Its pronouncable and branded though. Likewise domains were premium and were being sold for way too much on godaddy and elsewhere, like hbsly.com for $2195, bisby.com for $3000, bisay.com for $2988, bisny.com for $6795, bispy.com for $3546; these rates are from godaddy..
You can't base anything off of those automated appraisal scripts. They're mostly for novelty purposes. Your domain is good though because it's a .com and is only 5 letters long. Those are not easy to come by anymore. I wouldn't put a price tag of more than xxx on it though.
