Don't get the jaggy sand though Fishy!
I used actual underlay left over from laminate flooring - the expanded foam type - with only a little sand under the deepest area. Sand is the usual method because it's easy to mould round ledges and corners etc. If you're not going to be standing in the pond adn the ground underneath is fairly stable and smooth, I don't think it matters quite so much about having a really thick base, but if it's going to make your guarantee void then best to follow the rules
Lyn - the plants will die down for winter if they're not evergreens - just like in the garden. I always think it's nice to have a reasonable amount of those, especially if you can see the pond from the house. Makes a much nicer feature, and also gives more cover for wildlife. Even if it's shrubs as opposed to more traditional pond style planting, you can mix the two quite easily -Euonymous for instance, is ideal anywhere. Some of the Carexes are good, and things like Hart's Tongue Ferns. Caltha (marsh marigold) is almost evergreen.
Peat - I could send Fishy all the bumpf we've been getting about Independence
