Best place to stash cash for 3 years?

Hi, All. I am saving up to buy something. I currently have ±$10,000 and will continue to be contributing $1,500/mo towards my goal for the next three years.

I have been putting my money in smartypig.com with about 2% interest, but in my head I have been calculating interest as just a little bonous. However, I was wondering where else I should look to get maybe a better rate?

My money does not need to be at all liquid for three years so I figure that has to give me some leverage. CDs and all bank rates are terrible everywhere I look. I’ve looked at lendingclub.com and propser.com which may be possibilities though.

Any advice?
