Welcome to the TK forum Ned...
lol! I only pimp Ozone cause I really like the kites and I haven't had much experience with the newer Flexifoil or other branded kites.
You say you are wanting to get in to kitesurfing, my advice you be this :
If you buy a good branded kite (Ozone, Flexifoil) which have good resale value then you buy the kite and sell it when you want to upgrade to the water. To get you scudding the Ozone Samurai would do the job (so would the Flexifoil Rage) or the PKD Buster2's. The only problem with buying the PKD Buster2 is that because they are already cheap to buy, not many people will buy a second hand one unless you are selling it for almost nothing!
For jumping you would be wanting something with lift such as the Ozone Riot or Flexifoil Blades but neither of these kites are good kites for learning on because the lift can be unexpected at times. The other option is to get a depowerable kite which will prepare you for using a bar on the water, kites such as the Ozone Frenzy or Flexifoil Sabre or even the HQ Montana would be suitable for this, all three of these kites have plenty of lift for jumping.
With depower kites you do need to use a harness as well though, again this would get you ready for the water.
Now sizes of kites, I wouldn't jump with anything smaller than 5m. Smaller kites will lift but you will not get the all important float. For depowerable kites you would possibly want to say no jumping with anything smaller than a 7m.
With the stronger winds coming (we hope) it might be worth you starting with a 2m or 3m kite (not suitable for jumping) but gets you used to the basics of flying a 4 line kite and will get you scudding really well. The smaller kites will also fly around the sky a lot faster than the larger ones so you will probably have a lot more fun with a smaller kite to start with.
Hope I haven't pimped too much since I seem to be getting a reputation for it
If anyone who has flown other brands of kites could post some advice that would be good
