Are there actually any decent taps out there that don't drip?! I've got 4 pressure barrels (3 standard and a King Keg top tap) all with different taps and all of them drip, not massive amounts, don't get me wrong, but enough to be a pain in the arse! It's not all from the barrel/tap seal either, some are from joins on the tap itself, are the sparkler taps any better? Don't want to shell out for 4 of those if they're going to be crap as well?!!!
