+1200 on the Forward Seals.
They are more expensive, but they work wonders, particularly in low volume serving situations like you, me and the bumblebee homebrewer.
With the regular rear seal faucets, the beer dries out on the lever mechanism basically locking the tap closed with dried goo. The forward seals don't let that happen and instead you'll get an easy open without having to feel likc you're possibly breaking your taps, tower or bar everytime you pour your first beer.
If you have a frozen tap, you'll have to break out the hot water to clean it out.
