Do some research and you will see that there aren't many interesting SHA256 coins unlike Scrypt coins. TIT gets pumped from time to time, UNO and PPC might probably be interesting. Take care when mining PPC, high difficulty and low block reward, you need some hashrate to get reasonable results. NMC is merged mined with BTC. ASC might be something for you, you'll get some coins and can later convert them to LTC (not BTC) on Cryptsy https://www.cryptsy.com/markets/view/ASC_LTC
