If you don't want to drop $24 on a dripping atty, Liberty Flights has bridgeless SR and LR attys for $5. I like 'em, the last about a month give or take, and don't break the bank.
I have this exact drip atty, and it's a champ. I've considered going for one of the higher ends, but knowing that I've already lost one drip atty to my vents system I'm not keen on the thoughts of that much cash rolling away...
