Great idea... someone just starting out could get a lightweight rotary (like the Metabo or the
Flex 3403), then get the dynabrade attachment and use it til they felt ready to graduate to the rotary... and of course still have the functionality of the dynabrade when a DA is necessary to finish.
I can't seem to find the correct attachment on the Dynabrade site, though... can you post a link to the actual part?
