Yep, the Luxi F IMHO is quite a good tripod, light and compact, but not so good in any kind of breeze..
Unfortunately, you're not gonna get much for £30. I used to have a Jessops 323 and didn't rate it at all, even with a 400D and kit lens. Very plasticky and weak, plus pretty slow at adjusting, due to the ratchet lever action..
There are very good ones for about £70, mentioned in Photo Plus mag a few months ago. Can't for the life of me think what the make was, but wasn't one I've heard of before. Will have a look tonight and repost, unless someone else remembers what the make and model was?
Cheers, Mark
