You could do worse than get a Mju-II/Stylus-Epic, but unfortunately it has reached cult status. Inexpensive ones are getting hard to find. That doesn't apply to its predecessor, the Mju-I/Inifnity-Stylus. If you can get your paws on either of them for a fair price, you're a winner.
Which of the Mju-I or Mju-II is better is open to debate. The Mju-II has the faster lens, longer shutter speeds, and the spot metering option, the Mju-I has the far better viewfinder and, as far as I can judge, faster AF. As to reliability, the extreme miniaturisation of the Mju-II makes the film transport prone to breaking; I've had a couple, and they went bust after ca. 40 rolls. If you do get a Mju-II, stick with 24 exposure film, so the film advance/rewind doesn't have to work too hard.
