I have a recirc pump which I currently am not using. When I was using it, I ran it 15 minutes on and 15 minutes off. This proved satisfactory for always having warm to hot water available.
If your plumbing is exposed, insulating at least the hot line would certainly permit the above. You might even be able to go 15 on and 30 off.
