Transferring from Venice Treviso Airport (TSF) into Venice?

What are the most convenient, quickest, and cheapest options for transferring from Venice Treviso Airport (TSF) to the center of Venice? I realize each of these qualifiers might result in different responses, but just want to get a sense of my options, how much they cost, and how long they take. Much thanks!

Cheers,
Alex

There's a bus after every Ryanair flight.

Alternativley, local bus into town and then a train. Both are cheap and easy.
