I would never go for .87 as it is confusing number and forces the user to go out of the comfort zone. I would always suggest going after 9 or 7 at the end, and the full dollar. I have quite an experience in pricing, and prices ending with "7" helped to convert more on the fence users (and cheap ones too, so if you offer live support, I would avoid that), while with "9" I would get less troubling customers, but I would see a slight dent in revenue numbers (out of every 50 customers buying at price ending with "7" I would probably see around 3 less with prices ending with "9"). The sample for this is few thousands of customers, that I had to cater for personally.
