I am wary of these new inflatable names popping up where the business is registered to a private house with no shop as such. It makes you wonder what the warranty is worth because if the UK guy decides to sell double glazing instead next month then you're not going to have much luck with the Chinese supplier sorting out a problem.
Over the past 10 days there seem to have been some very good value, apparently immaculate, Zodiacs, Quicksilvers & Honwaves on Ebay. I'd rather go for used up to a few years old in a major brand.
