Like you I've just bought an Acer laptop (5920) running Vista. Unlike you I already had a colour laser printer - Samsung CLP300 click here and that works well with Vista and XP. It comes with a separate Vista installation CD.
Like all colour laser printers the replacement toner cartridges aren't cheap (black, yellow, cyan, magenta) so it depends upon how many pages you plan to print! You can buy refills and the CLP300 cartridges should be easy for DIY.
The CLP300 is reasonably quiet when printing (some roller noise as the paper goes through the printer) and is otherwise silent.
