Here's a rather grand cuckoo clock I found listed on eBay. This clock already has many bids on it with a fair amount of time left. I don't know much about cuckoo clocks, but this suggests to me that this is a good one. Those of you who know more about this sort of thing: please comment!
This listing features many nice detail photographs.
Here the eBay listing for this large carved wooden cuckoo clock with automata figures.
