The Herschel Wedge is an older style 2" Baader unit with a superb Zeiss prism and is in great condition. It is the visual version with the ND3.0 and Solar Continuum filters (both required to be used).
I've used it numerous times on both 120mm and 150mm refractors for stunning white light views of the Sun. The wedge comes with Baader Solar Continuum and ND 3 filters (both are required to be used). Excess heat is radiated out the rear of the unit.
I am looking for around $550, plus postage at cost. The Cool Ceramic visual version is currently $929 at Testar.
