The XXL ultra light hammock from TWHammocks might be worth a go at £18.99. It's got the length you might find useful and appears to be cheaper than DD equivalents.
Don't bother with a net initially unless you're​ in midge country.

I've not tried their hammocks but have got one of their tarps which is a great piece of kit.
Side note: If you get a larger/longer hammock than usual (which I personally I prefer) be aware that you might need to get a bigger than average tarp to cover it.
