Hey man, read the thread on the second page of FTM Gear called "Binder comparison chart. It has reviews on Underworks, Les Love Boat, and other binders. Also has some pics that might be helpful. Don't worry much about your sizing, each company has a place on their website where it shows you how to measure correctly to get your size. I don't know any UK specific companies, but all the companies I know of will ship there. I don't know how much shipping is, but I'm sure it's reasonable. I've tried Underworks and Les Love Boat binders, and I prefer the Underworks tri top for everyday use, and the jersey mesh model from Les Love Boat for hot weather/swimming. I don't really like the Underworks double front, but other guys swear by it. Just do your research and I'm sure you'll figure it out! Hope this helped!
