How good a deal do you need to make when buying a Festool OF1000?
While it is true the newer OF1010 appears similar and they do share accessories, there were internal improvements. Also, the newest OF1000 was built in 2005, so the sate of bearing lubrication has to be questioned.
The USA$ price of the OF1010 new is $410.00
Good used OF1010 can be bought for less than USA$300.
So, use your own judgment buying an OF1000.
