That's a really impressive lineup you have (and I agree that TOTAN would definitely be the one I would give up).
If you are looking for a recent machine, I would recommend BM66, DeadPool, or the new Jurassic Park.
Seeing as how you seem to like the '90s B/W machines (as I do), I would also suggest RoadShow. I've always found it to be an underrated machine of that era.
