Coleman stuff is generally pretty far from cutting edge in terms of weight and sometimes features, but it is usually well-made and pretty stout.  I would advise figuring-in a couple of pump re-build kits (cheap) as this is a wear item, and a spares for each generator that it uses for the same reason.  Check Coleman for spare parts, and know the exact model of your stove, as they've made a lot of different versions of this stove over the years.  If the stove is used, try to examine the inside of the fuel tank as best you can.  Visible rust is a disqualifier.

The stove pictured by OP has the much-preferred circumferential wind screen.  It's the 1/2" high band around the bottom of the burner assy.  The older stoves lacked such, and suffered for it.

The newer stoves are improvements, for the most part over the older stoves.  Now, it might be possible to retrofit the circumferential wind screen now offered on stoves to some earlier stoves.  I'd consult experts on such stoves about doing so, and the internet will reveal such.  The parts required to do so should still be available from Coleman for cheap.

IOW, If I had an earlier Coleman stove, such as pictured by other posters, and it lacked the modern wind screen, I'd be all over how to retrofit. I've heard some complaints about this sort of older Coleman stove blowing out in strong winds, and so the new circumferential wind screen was developed as a response to consumer input.  The big "X" screen centered over the stove burner (alone) was a semi-successful attempt to remedy the windy blowout problem, which was finally solved by the circumferential wind screen along with the X screen.  In combination, they solve the windy blowout problem, and transform the stove into decent kit status.
