I live in California, the electricity is not cheap. And paid for out of my own pocket, not on a business ledger.
From a stats-keeping standpoint, restarting with lower totals (and ones that rise slower) would be nice. But I've pretty well covered the integer overflow problems.
My vote is to keep the stats units I've paid for, not to put them out to pasture. My total is not in the Top 10 (or anywhere near), but it still kept my bedroom noisy for weeks on end. Slowed my games down too. (serious sacrifice there )
