Pea/Bean Netting?

Does anyone use it? That plastic square stuff.

I got myself some jute netting once and it only lasted one season and cost a fortune.

I need to use the nets to keep my flowers straight. Just planted up some foxgloves and some campanula.

For the dahlias I have used old poultry netting ( some squares are a bit small but I can keep reusing it so that's good for me.

I need mine at least 1.5 metres wide...my beds are 14 & 30ish foot long - any idea where I can get some at a decent price.
