If you have a monitor with VGA and either a SCART, SVHS or COMPOSITE input (an LCDTV for example) the choice is a little more difficult.
If you dont, then there isnt really any choice. You have to get a PicassoIV.
PicassoIV = ~£150 ($300)
Mediator A4000D = £205
Voodoo 3 PCI = £10
Internal Scandoubler = £100+
Monitor Switcher = £20
Total = £335 ($700)
Plus I am not sure a Mediator A4000D fits in the Micronik case which may mean you need a new case. Anyone know?
