A little addition to that:

Within Europe good deals can frequently be had in Germany - but
certainly, UK and US are good too. I bought my Ultra10 locally (NL) from
someone who didn't know anything about it for EUR 25, turned out to be a
440MHz maxed out with 1GB of RAM - that was sheer luck, but all other
components I later installed (Creator3D UPA video card, SunPCI II, that
sort of thing) I bought on eBay. Situation in NL is similar to Italy,
with very little choice or value on ebay.nl, so the Creator3D came from
Germany for EUR 10 and the SunPCI II for USD 25 from the US.
