Thank you very much for sharing the photos Chris! It certainly didn't make make the decision easier...

They are both very nice, each in its own way. For running at my own, yet to be railway, the Bertie is fine. If I want to bring a loco too a meeting, it would be better with a loco with RC and real reversing gear.
I have yet one more day to make my decision, and either way I can't really go wrong. But if I'm starting with a Bertie, the desire for a "real" engine with always be there. So in the far run, I think I will benefit from purchasing a Argyll right away. The snow is still deep here, and I can't start building tracks for a couple of months yet. So instead of getting all I need at once, I perhaps should get the Argyll only, and buy tracks later. I have much fun just watch those beutifull crafted gears move. So getting a pair of rolling road units could be the ting for me now.
