I purchased three refurbished Lenovo's in January from two different companies on Amazon. The worked well for office use and initially seemed like great buys. However, as of September the hard drives have crashed on two out of three.Fortunately hard drives are inexpensive, but it is time consuming to replace a hard drive and rebuild the system to how configured. If you are getting one of these, I'd suggest making a drive image once set up. Obviously make sure all data is regularly backed up.  It might be even better to just put in a new hard drive from the start.  In the past I was able to  find hard refurbished computers which had a new hard drive put in by the refurbisher. If you find an option like that, I'd strongly consider it, even if more expensive.
