I think there's some funny business in every election (dead people casting absentee ballots and whatnot), but usually not enough to change the result. Certainly there's room for improvement, but I still regard the results as legitimate. What's the alternative? If you want to have input into the government, you have to work within the system.
Here in the U.S. state of Rhode Island, we use the type of ballot where you connect an arrow and then a machine reads the ballots and counts. Since we're actually marking a physical ballot, there can be a manual recount if someone suspects that a machine screwed up.
(There's an example of the ballot I'm talking about here:
