Brompton derailleur/tensioner options...

Inspired by my other thread about winter, and this video that I posted on YouTube a couple of years ago, I wondered if anyone has any recommendations for alternative derailleurs that aren't fully enclosed with the chain guides so they're easier to clean.

Be great to get some first-hand reports.
