I have a 16" GSO, and made a new collapsible base out of marine ply. It is lesx than half the weight of the production base and very stable and smooth. In making the base I was also able to lower the overall height of the scope so no ladder is required to reach the eyepiece at the zenith position - just a small box.
If you can't make one yourself, and it is easy if you just copy the production parts, there are kits available, pre-cut in nice furniture grade birch ply, by Dennis at Dob Stuff, and there is a guy on IIS that makes them as well. Nothing will be as cheap as doing it yourself - don't be afraid to try.
