iMac 700MHz - Memory and availability?

[Malcolm Burtenshaw]

I've been looking over older mac models and my sister might benefit  
from a 700MHz G3 Indigo or Graphite iMac. It looks like it takes  
normal SDRAM. Is that true because I have twin 256M sticks for it if  
it is.

Also, does anyone know if any 700MHz iMacs are available over here  
for purchasing second hand. I've checked eBay and got a bunch of US  
sellers but would prefer a local source if possible.
