Not sure about the boots. Two issues. First, and the major drawback is that they are only waterproof up to where the rubber joins the PVC material which makes them little better than a waterproof shoe. To get an idea, think of a waterproof shoe with a gaiter attached. Second, the sizes are on the large for the stated size, try them on before you buy. I bought a pair a couple of years ago. They aren't badly made but they have sat in my garage virtually unused, which probably says it all. I can't really find a use for them as they don't seem to tick any box!
The Aldi balance can be bought from Home Bargains for £1.49, not really what I was looking for as I don't catch too many barbel approaching the 50lb mark. Essentially, the scale is too crude for my liking. Wilkinson did a digital one for not much more than a quid and is surprisingly accurate. Incidentally, my best barbel p.b. is 36lb. Should have posted this on the Barbel p.b. thread.
