I'm losing hope of seeing a refurb anytime soon. That and I have my doubts it will be much less than $350. I see new ones going for about $399 from us sellers but I'm open to ordering from any reputable dealer even if it is overseas.
Someone on another forum posted a good deal from Henrys in Canada. They have both the silver and black version on sale for $299. With shipping to the US and figuring the exchange rate it comes to about $287 US. Heck of a deal. Expect to wait a few days for delivery though. I believe the site said 7 to 14 business days.
Don't feel bad,I just, just bought a used, though mint with a B+W filter for $375. A day or two before the Henry's deal I saw that the lens was back-ordered at Oly's site. My logic, flawed apparently, was, "Who would put on sale a item that the manufacturer has run out of?"
If you are not opposed to getting a used copy, keep your eye out over at KEH.com
I've bought a lot from them over the years. They have a very aggressive rating system, so even bargain items are in decent shape. They offer a 6 month warranty on their used items, so you definitely have a good backing on anything you buy from them.
Here is a link to their Olympus m43 fixed focal length lenses. I did not see any 25mm today, but they get new inventory in quite frequently.
