There are many version of the Rodagon 105. The older, the cheaper, generally. Also, don't confuse the 'normal' Rodagon with Rodagon-N 105 and Rodagon-G 105 which are both extremely expensive compared to even the latest 'normal' Rodagon 105's.

Thanks for that ! I will check what I have been offered !!

Apo-Rodagon N, that would be (AFAIK there is no "plain" Rodagon-N).
Newer lenses generally fetch higher prices as they are less likely to have age related problems (scrachtes, dust, haze, fungus), they also often have better coatings. This is true for all brands of enlarger lenses. In the case of Rodagon, there is a second aspect, as some of the older (silver and black barrel) Rodagons are prone to develop problems in the form of lens separation (delamination). A lot of the dirt cheap older Rodagons that can be found on Ebay are suffering from this.

Yes, 'APO-Rodagon-N' in 105mm. Note that there are also earlier 'APO-Rodagon' (without the 'N') lenses in the Rodagon line but not in 105mm. A list is here if you are interested; http://www.photocornucopia.com/1061.html
