-----------------I know for fact what sold to commercial 3rd parties and the diy crowd, (when i was there) ! the commercial was 100 fold compared to the diy! but like i said i left over a year ago! so i have no idea who this is being sold to commercially these days! you are starting to sound bias ....to certain places, i have posted many options no bias here...
If you're not bias then why didn't you mention OpenDTG?
If you haven't heard of OpenDTG then your truly out of the loop.
FYI, looks like Spectra DTG is also out of business.
