A taller tire will have a bigger sidewall. This will ride slightly better due to being able to absorb and cusion more and at the same time handle slightly worse due to being a little more mushy.
Go with the 165R15 or 165/80R-15 (same size tires). There are a lot of different manufactures. eBay can get you a pair delivered in the U.S. starting at $120.00 and go up to about $180.00 for the more expensive ones.
