http://www.kitepaddlesurf.com/searchquick-submit.sc?keywords=Grom$280 has got to be the best deal around that I've seen for a new kids board with pads and straps. I've bought from Andy many times (despite the fact that I live on the completely opposite side of the country) and the prices and service are top notch.
I bought my 12yo daughter a used board from Real last year and then still had to get pads and straps and ended up spending not much less than that for a board that I had to fix up a bit. Wish I could have gotten this deal then.
