I've used my oil extractor numerous times, but on other cars/trucks, not my boxster... less mess and reduced risk of burning yourself with hot oil.
I read somewhere that it's not possbile to use an oil extractor on a boxster:
Oil Extractors-Anyone Used on 2005 or newer Boxster?
But I've never actually tried. I think i'm going to give it a try during my next oil chance since i don't understand why it wouldn't work - if you try before then, let us know if it works and I'll do the same if i do it first.
Only caveat i can think of off the top of my head is maybe you need a longer extraction tube to stick in to the dipstick hole because the boxster dispstick is longer than any other dispstick i've ever seen.

I know of 2 oil drain valve devices that FrayAdjacent makes reference to:
1. the FRAM sure drain system (which I don't think they make anymore because it's not listed on their website) but you can google it.
2. Fumoto Valve

I've used the FRAM one before on other vehicles, works great.
