After having testing the Hirsch focal reducer for months, I think that it's a very good option from the MEADE and Celestron ones:
I could compare it with the Meade original, and I didn't find differences between both of them in terms of optical quality and luminosity.
It is a 4 element design, as the Meade 4000 series. By using it, reduces the main telescope's focal ratio by a factor of 0.63 (e.g. from f/10 to f/6.3), so a 2000mm of focal length would be a 1260mm... yes, reducing the main focal, but dramatically increasing the luminosity of the telescope.
A low price and high optical quality recommends it as a very good purchase option regarding most expensive ones from the well-known brands...
