0.8x 2" reducer for my 100ED / Quark

[Bender]

Still debating the best way on how to improve on my 100ed / Quark combo. I got a TV 40mm plossl to get the magnification down and would like to go a bit lower. As a reducer in front of the plossl wouldn't help with the small fov I rather try to use a reducer in front of the quark.

I saw a picture from Stu, he had the Orion 2" 0.8x in front of the quark.

 the 0.8x would get me down to an fl of 7.2, still within the recommended range.

Looking for recommendations for a reducer with filter thread to fit my 2" UV/IR cut filter in front. Idealy with a 2" nose piece and a T2 thread on the other side to fit a 2" ep holder. Don't wnt to spend more then I have to, but on the other hand after investing in the whole set up, dont want to save at the wrong end either.

The Baader 2" deluxe ep holder has a light path of 53mm, close to the 55mm back focus recommended. Not sure though where exactly the focal plane of the Quark is.

The versions from Orion, Altair Astro and Long Perm look all similar, but show a wide range of price

Then for twice as much is the TV reducer
