Nothing is more annoying that hosting a holiday party and mixing drinks for everyone -- you end up working rather than enjoying your party. And sure, you could hire a bartender, but a bartender who actually knows how to make a drink that doesn't have the ingredients in the title isn't going to come cheap.

I have a suggestion -- the Lazydrinker. It's not exactly cheap, but once you purchase it, all you have to buy is the booze (well, that and a CO2 tank) -- the Lazydrinker then makes the drinks for you! You can choose from either a 16 or eight valve system, depending on how many liquors and mixers you plan to use. And, if you want to have more booze from which to choose, you can hook up multiple systems and, with the Lazydrinker database, you create more than 5000 drinks!

Every drink is perfectly mixed, solving the problem of whether you added one or three jiggers of tequila to your fifth margarita -- I know, after a while, it's hard to keep track. Prices range from $90 for a total DIY kit up to $750 for a fully assembled 16 valve Lazydrinker, and you can get yours here.
