Depending on what you want and how much you want to spend, I would recommend a Fleshlight if you have some change to spare. They last quite a while if you treat them right. They are good enough to lead to orgasm, but the feeling isn't super-realistic. It's great stimulation, just not very "organic" feeling. If you don't mind getting a one-time-use masturbator, I would highly recommend the Tenga air cushion cup. It feels amazing, and very, very, very real. The downside is that you can only use it once or twice (unless you use a condom, which I haven't tried doing).
