Depends upon what radio you get, and what you want to do with it. Unfortunately, FM work all uses vertical polarization, and SSB work all uses horizontal polarization, and there are great losses when using a beam having the wrong polarization for the mode.
Having been on two meters for over 37 years, and on all modes, if you're getting an "all mode" two meter rig that works both FM and SSB, I'd recommend a good vertically polarized omnidirectional (gain) antenna installed above a good horizontally polarized beam antenna, on the same mast. A rotor can turn the mast, and both will rotate, but the vertical antenna will have no directivity, which is ideal for working mobiles (constantly turning a beam to keep up with a mobile driving around is a real pain, and wears out rotors quickly).
For a good "starter" setup, I'd recommend a couple of my personal light-weight but high-performance favorites: The Diamond F23 ominidirectional vertical (only weighs about 4 lbs, but works extremely well), and the M-squared 2M9SSB horizontal beam antenna (9 elements on a 14-1/2' long boom, great gain, great match, excellent antenna but only weighs about 5-6 lbs). Both can be installed on a single 5' mast atop any medium-duty rotator, and their performance will amaze you.
I wouldn't go shopping for two meter beams on eBay.
