What do you do when you can't find anything to add?

Was curious to know what people (in this kind of spot) find themselves doing.

Over the last few months for me, almost nothing has come across any of the major auction houses or eBay that I really feel I would want in my collection. My Jackie Robinson/integration themed collection has most of the "major" pieces I am interested in, except for a few items that I expect will be exceedingly difficult to find. Almost no vintage lineup cards of any sort have been listed, and there has been little in the way of WWII-related baseball items.

For me, as I left my previous job a few months back, and have been working on launching a business, the timing has been fortuitous, and I would not be in a position to buy much of anything if items I was looking for did show up.

That said, how do you handle slow times in your collecting? Do you save up money for when the (inevitable) rush comes? Do you expand out and buy other random items? Do you try to find another area to collect?
