It really depends what you want, from the cheap and cheerful candy striped beach type, cheap wooden poles that bend and split to the Isabella Linea, currently at £252 (for a windbreak??)
On paper the Isabella looks superb, robust and very clever, but for that price I would suffer the wind. Some time back we grabbed a couple of Outwell ones and they worked exceedingly well until madam reversed over the nearest one. It was my fault, if I hadnt wanted a pint, she wouldnt have had to drive and therefore the windbreak wouldnt have been crushed. Hows that for logic. Anyhoo
