When buying a Mac, given the choice between new and retail price, and Apple Refurbished at a decent discount, I would go for the refurbished every time.
I have purchased a lot of Apple Refurbished devices over the years, with a few Macs included, and they have never disappointed.
Actually, my 2006 Mac Pro 1,1 was an Apple Refurbished Mac, I purchased it as soon as the refurbished Mac Pros started showing up in the Apple Refurbished Store. It is still daily used, and has never given me any trouble.
I would purchase all Apple Refurbished Macs, but the trouble is the wait until they start appearing in the Refurbished Store, and then trying to find the desired configuration. If you find it, you got to get it quick, because they sell quick, and that configuration may not come back for a long time.
It could actually be less "risky" to buy an Apple Refurbished Mac than a new one.
What I am about to say about Apple Refurbished products, applies to the US, as I am unsure of how it is handled outside of the US,
Apple Refurbished Macs are tested well beyond the tests that the new Mac are subject to, so (in theory), the Apple Refurbished Macs that pass these tests are less likely to develop problems due to a manufacture flaw, such as a faulty component.
A side note, again this applies to the US and maybe elsewhere, but in the in US there are no consumer protection laws governing what constitutes a "refurbished" product. Anyone that sells a something called "refurbished" could just mean that the seller or business wipes the device down with a damp cloth.
Apple advertises its refurbished process, letting the customers know what to expect.
Basically, a refurbished Mac sold by anyone other than Apple is not the same thing as an Apple Refurbished Mac.

Apple used to have a more detailed description of their how they refurbish their devices, but they seemed to have shorten it a bit.
