I've purchased refurbs from Accessories for Less and have been happy with the product. Wouldn't worry about it.
That said, I do agree that the Boston's are fine speakers, but you might be able to find a something better for the money. The retail savings listed on the site is sometimes a little generous.
Those RBH speakers look like a great deal. Try to stay away from the HTIB.
Is it solipsistic in here, or is it just me?
