I have been using my sj4000 for the last week or so. Gonna try it out for what I intended (Videoing the daughter rock climbing) tonight.
Was at a wedding at Lake Garda last weekend and it did as good a job as the wifes iphone did on stills and the videos were acceptable in a kinda 1st person close up way.
Quality is fine and now that I understand how to use the software for the ipad I am getting along fine with it.
As it matches the gopro I can use any of the accessories on ebay of which there are loads.
I went for the wifi version but the non wifi version sells for unde £50
