Thanks to all for the info, it is very helpful.

There is another thing, and English members please take note:

browsing in Ebay shops, in ebay.co.uk, I noticed that UK prices, (when translated to Euro) are usually cheaper than the German equivalent. For example, a Casio WK will go for 550 Euros in Germany which is about 330 quid, and is around 250 quid in the UK, the differnece is huge. Is there a catch?

Andrea,
Cherubini really seems to have a lot of items and in good prices. I don't know Italian, but I can understand almost everything, considering that most of the roots of the words sound familiar in English, especially in technical specifications. "Tastiera dinamica a 76 tasti" and "Sequencer a 6 tracce con 5 song ed una capacità pari a 10.000 note" pose no problem at all.
