Try SpectreCoin. Compared to other privacy coins it's very cheap, even at $1.75 right now. In addition, unlike some coins that are marketed as privacy coins, XSPEC actually has good privacy technology incorporated into it. It uses Ring Signatures, it's integrated into the Tor Network and uses OBSF4 obsfuscation so it'll work in places that have blocked the Tor Network (such as China), and a number of other things. Auto scaling ring signatures and default stealth addresses, among other things, are on the road map for future releases. A new release is due to be sent out before the end of the year (if I'm not mistaken) that should include a few additional privacy features.
