In reply to teddy_simmon:
I have quite regularly used this type of shelter(MLD Trailstar, a Solomid,a Patrol shelter and a Golite SL2) for the last few years in Scotland in 3 seasons and with caution even in winter,and they do work well. I wouldn't want to use them without an inner net, for midges and stuff. In most cases inners are being sold separately- and hard enough to source- something to consider regarding the overall cost.
With a bit of patience you can find second hand MLD shelters on outdoorsmagic or ebay, or probably cheaper, something like a Golite Shangri-La 2 or 3. There's two online shops I can think of that will probably have what is currently available in the UK, probably not much as it's more an American thing, but I think there's a company now that copies the Golite shelters after they withdrew from the European market.
