I had a secondhand Y8000 but I sold it on a while ago. It ran well but it was looking a bit rough around the edges and the model needs a detailing kit to bring it up to standard, in my opinion. I'll probably buy another one at some stage and detail it, though, because I do really like those locotracteurs.
The 68000 is nice, but I've never seen photos of one running on Le Cévenol - at least not in the last 10 years or so - so I couldn't justify the cost of buying one at the moment. Fab-looking loco, though!
