I've had one of these for several years now and it has given sterling service for all basic computing needs. The HDD is small by todays standards (this model is probably four or five years old). It will provide excellent service for word processing, spreadsheets, internet access etc.
I don't know of any sites but the last contact numbers I have for the medionUK hotline (admittedly from 2 years ago) are: 0870 727 0370, 0870 729 7712 or 0870 727 1818.
The last medionuk address I have is: Medion House, 130 Faraday Park, Faraday Road, Dorcan, Swindon, Wiltshire SN3 5JF (01793 715715).
Hope this is of some help.
