Ran, you bring up a good point, but there have been times when they aren't originally $25 notes (granted there aren't as many). If you have a fair amount invested, you can look at these notes portions that started at 50, 100 or more. Availability should get better as time goes on, but perhaps folks will find ways to automate strategies like this. I've purchased over 180 (over 2k in the portfolio) notes using this method and have been happy with the results so far. It's a great way to diversify in my opinion.
