I am sure you could get cheaper versions. Like having the sale material but not the mechanism, which I assume was the dearest bit. Outside shops in Fethiye they hook the material up outside the shops and tie the bottom edge to the ground by strings.
This shop does the stuff that zips into place like Mustapha's used to have at Cadianda 1. I recon that'd be a better dust reducer than what we have just had done. ~Because of the mechanism, the blind hangs away from the posts by about 3". They're very nice people, it might be an idea to go get a quote. Then as you leave the shop, if you turn right go across the roundabout and up towards Tasyaka there's a little place on the left about 1/4 mile up (if that) that friends used and were happy.
