Well to be honest the DFT vs the 6000 model are about the same, the bigest difference is that with the 6000 you can store readings and with the software you can down load them o your laptop and print them off.
Sounds to me like the DFT is more for your need, if all you want to do is take readings then the DFT is what you need. Besides the price is definetly right for the DFT
the 6000 has many, many more features but that's just the main one for me
