First of all, thanks again to everyone who answered my question. Once again, I'm astonished by how helpful the community is around here.
I ordered a warranty extension from Epson a few days ago, since my original one-year warranty was going to expire in mid november.
One thing I don't get though, is the price. Here in France, the warranty renewal costs 1020 EUR excluding taxes for a 3-year extension. Someone said earlier in this thread that extensions costed about $700 a year for a 7900. On the price list on Epson France, there is no word about a yearly fee. Does that mean that I will be charged 1020 EUR each year for 3 years ? Can anyone in France or Europe confirm this ?
