For beginner, check the merchants and compare these choices:
1. EXP with handles and lines (lines should be Laser Pro), used to be a common starter package.
2. SLE standard PLUS handles PLUS lines. (Or may be packaged as RTF - Ready To Fly)
3. B standard PLUS handles PLUS lines (Or may be packaged as RTF - Ready To Fly), which should come with TWO sets of frames to handle a wider range of winds.
If in doubt, contact any or several of the excellent merchants that advertise on this forum or the KiteLife forum. Select option 1, 2, or 3 in that order depending on where your wallet might start crying. They are all excellent for a beginner. But if you have not had prior experience, it might be better to start cheap. Many people do not have the opportunity or the drive to master the quad kite - and unfortunately drop out.
If it helps you decide, I am a non-athletic senior citizen (i.e. elderly couch potato), and have managed to reach a fairly comfortable advanced stage - certainly NOT a master. But that has taken several very enjoyable years to do so.
