I have the LS130 with all available attachments, and previously owned the full Porter Cable Profile sander kit.
I much prefer the Festool, though the PC had more esoteric profile options included. The fact is that I had a number of profiles in the PC that were never used, but have used the LS130 profiles on a much more consistent basis.
With the addition of the RO90 Delta pad, I have next to a complete profile and edge sanding system. I 'may' add the DTS400 in the future....just because it's green! [smile]
Cheers,
Frank
