Well, on my WellsGardner you had to order the power-cord seperately. Look at
http://www.wellsgardner.com -you most likely get the best price if you order directly from them. Ask the shipping-costs before, for me it'd have been $347, but I'm located in Germany!
I've got a 19" U3100 -its very cool & authentic looking, but windows looks also poor on it. I guess you must decide between authentic arcade-game or kind of blockieness when you want to use it addition for PC-games, Internet and more.
First I wanted to make it all, but now I realized that it's just stupid for me to do everything with it - Hey it's supposed to look like a cool arcade-cab, and not like your local internet-kiosk! Anyway, I've three PC's (including an old Laptop) that are connected/connectable to the internet, so why should I do anything different then arcadegames on my cab?
If you wanna see some pictures from the monitor in action, you might look at my page. This monitor is only available as 14" & 19" - I didn't want more anyway 'cause most all classics did go with 19", plus I make it rotable anyway.
