I know of 2 guys that are keen to get into kiting just recently,
Both bought full kit off Ebay,kite,board,harness,bar, pump package for they bargain price of around $500.
Both bought really crap gear,not worth a cent.
If you dont know what to buy as a leaner,dont rush in and grab a bargain on ebay without someone who knows a bit about kiting looking at it first.
There is the odd bargin on ebay kite gear occasionly if you know what your looking at/for. Specially this time of year,ending of season, with some people selling their one season old kites/boards on auction,but you need to know what your looking at.
If it seems too good to be true.......Its is too good to be true
