Seriously though, what are you planning to do? Closed-cell foil if you must have a foil, or an inflatable kite will do fine...

horses for courses,
beginners need inflatables for water, foils for land
only more experienced can use foils for water, or inflatables on land,
pump ups fit both bills only if you are serious about water,
used to ride buggies, mountainboards, and big water directionals on foils,
now rip on one size inflatable kite in all disciplines,
any easy late model lei kite, stable and depowerable may suit you

Most LEIs are pretty good for land boarding. I actually prefer LEIs in my local conditions as they tend not to get bow tied during the lulls (I'm comparing four line foils rather than the closed cell foils here)

I personally think it helps if the kite can be reverse launched. I have a Naish Ride that works pretty well because (cheap, reverse launches easily, light weight so stays in the air during lulls pretty well). I'm sure other kites are equally good or better but I tend to see a lot of ex demo and end of season Rides at the same price as 3 year old second hand kites round here.

The "down side" of foils for land kiting is that they can twist and collapse when a sudden lull comes and then when the gust comes back it doesn't suddenly pull you like a truck because the foil has to re-inflate the wing tips and this gives you grace to control the kite, ditch it, etc. But with LEI kites, they hold their shape and could collapse upside down in a lull, but if a gust comes back they could quickly pull you like a truck and put you in dangerous territory. When land kiting on the beach, it's safer as the wind like normal kite surfing is more stable and consistent. Land kiting on a salt flat way in land with no hills or trees nearby is also the best. It really depends on where you plan to land kite. Stay safe!
