I have a standard 18-55mm and a tele-zoom lens (cant rember the size) but i really want some thing to take landscapes. Thing is there are so many types so was wondering if one of you Pros could help.

Thing is Im looking at Jessops website and confused on the descriptions.
One in particular the focal length is 24mm yet another says 10-24mm.. so which is the better ?

In a nutshell can someone advise what kind of wide angel lens I could go for ?
Sadly Im a tight arse or rather to be honest not flushed so around the 200-250 mark would be ideal That said Im waiting for someone to say dont bother on that price
