There should be no fear of clipless.

M520's are probably the most popular clipless pedal on the planet and dirt cheap. Just practice on a grassy field the first time.

Remember that there are two kinds of cleats. SH-56 are going to be easier to get in and out of but less secure for aggressive riding and racing. SH-51 are going to be more secure if you ride hard but slightly more difficult to clip out if riding casually. That said, many people use the SH-51 cleats without a problem.
