If you're handy with Linux or happy to learn, setting up clamd on a Raspberry Pi (or similar low power, low cost ARM based computer) may be an option to permit 24/7/365 staking. Only downside is that because RAM is limited, you'll probably only be able to run one or two coins on it. I gave up trying to run both CLAM and ORB; the computer was constantly swapping to and from the memory card (ouch).
I've currently dedicated an Odroid C1 (USD$35, quad core ARM @1.5GHz) to CLAM, but I've just realised that I could even run the daemon on my Pi based security cam... a security camera that generates coins!
