I started with the Garmin 196, nice and simple, quite cheap also. Then upgraded to the Garmin 296, just had to get some nice color. Then I wanted the nice terrain and faster processor, with the addition of private airports, so I upgrade to the Garmin 495 (this is the one without the onboard weather subscription). I really like it, just big enough to see, but small enough to not take up all your panel space.
