I have just purchased a Logitech Web-cam C120 from STAPLES priced at £9.99 inclusive VAT. It works perfectly with Linux Mint 9, Skype, and Ubuntu 10.04 Skype and Cheese. It also works with windows X P Home.
Further I purchased a HP Printer/copier/scanner HP2400 series which also works with "Simple scan" on both Mint and Ubuntu.Prints,copies,Scans perfectly.
Installed Xsane and that App also works with the added bonus of being able to scan any size photo negatives like the old plates from projectors and 120 camera negatives plus 35mm negs in colour or Monochrome. Experiment with the set up to get best results small negs require high pixel counts to get best results.
