There are also the perforated 'mesh' dishes e.g. Maxx Digital. They are lightweight and fairly see-through and can be easily camouflaged with plasti-kote spray paint. As they look smaller than they are you could go for a 90cm and get more gain for the weaker channels.
Here is an example of a camouflaged perforated 'mesh' dish.

Note that he should have also spray painted the cables, diseqc switch cover, LNB brackets, LNB holders and the LNBs (but not the white cap at the front that the signal goes through). If he had done that it would have been almost 'invisible'.
Compare that with the install at the start of that thread.

That carbuncle should have been spray painted with Plasti-kote Ice Cream Matt or similar. Then it wouldn't look like the house has a big blackhead zit on its face.
The most useful Plasti-kote colours are Red Oxide Primer, Ice Cream Matt, Chocolate Matt, Shamrock Green, Hunter Green Satin, Grey Primer and Grey Matt.
If you wanted to make a feature of it you could use Butterscotch Matt or Scarlet Red Matt or Orange Gloss. Some companies use red dishes in Asia and they look good in sunny weather. Also take a look at the cheerful Balamory style Televes orange yellow dishes.
