how much RAM is really worthwhile and useable on an A1200 and would I get any benefit from whacking 128Mb rather than just 16MB?
If you're only playing games and doing some random Workbench stuff then you are pretty much safe with 16MB. But like Caius wrote, if you do a lot of big graphics/audio stuff then you might want to plug in some more.
In my A4000 I have 272MB Fast RAM, which is a complete waste normally, but I already managed to have "just" 70MB free memory left when I had a few audio things running...
