So I decided to go with the Provent 200 for my HDJ81 and if anyone is looking to get one as well, just order all the hardware online. The Provent itself comes with nothing if ordered on amazon. So I found some threaded 19mm adapters from AU and hose that I'm waiting on now. Does anyone have some good mounting ideas or pictures? I've seen a few on here, just wondering if there are some new ones around. Being in Japan has made finding the right hoses and fittings very difficult, I have been to too many stores looking for those pieces. I'll add some pictures of the process when the parts are in.
