Hardware for sharing monitor, keyboard mouse !

My new PC set up is terribly swish - DVI output and a DVI monitor. Problem is when I get older PC'S in for repair they come with VGA - with means im under the desk with cables here and there .....I know there a switcher boxes - can any recommend a decent value for money one (uk based)

you could use a KVM switch ,or a vga to dvi adapter , i live in Canada so cant help with were to buy one in the UK
I have/use a 35.00$ cdn Iogear vga, KVM switch ,low cost but work well for what i do with it.
i have a separate monitor and keyboard and mouse setup for working on customers computer right now
mine similar to these 2 port ones, good luck
