After three years in acquisition mode I'm beginning to think I've bought virtually all the rolling stock and locomotives I want for my model railroad. Even the ads aren't all that enticing these days. I look at them (the new Athearn FP-45s in HO, for example) and think, "very nice, but do I really want to spend $135 for it? Nope." I have given deposits on two diesels on pre-order (where they've been for over a year), and I am looking forward to getting them, but lately, I look at what I've already got and more often than not think "maybe I ought to sell some of this." Example: I have four Challengers -- and two of them are still in their boxes. Has anyone else been though this phase? What happened next?
