DFI 5 vs DFI 6 experts please

I have a DFI 5 controlling a minirammed 406 solid roller motor. Is the upgrade to a DFI 6 worth it?

I don't have the money any time soon to go to a FAST system or a DFI 7 but I know I can pick up a used DFI 6 on ebay for 200-300. Are the features of the DFI 6 worth the upgrade and if so, what are they?

If you already have the DFI 5, stick with it and just use Calmap 6.0 or 6.32. Internally, the DFI 5 is practically the same as the DFI 6. Hope this helps.
