Okay, I'll just wait for a good deal on the 1.25Ghz or 1.42Ghz model.
The 1Ghz eMac uses PC133 RAM and only supports USB1.1 anyway.
Dunno where you are from, but I just saw an 1.25 GHz eMac on ebay Germany, currently at 1 EUR:

But I'd rather go for a PowerMac G4. They aren't that much more expensive than an eMac and you are free to attach a bigger display and you can - depending on funds and demand - upgrade the cpu up to 1.8 GHz. If funds are not too tight I recommend a Mac mini G4 1.5 GHz - I like mine very much. But the 1.5 GHz models are rare and usually go for 200+ EUR.
