I'm interesting in purchasing a spiral saw......... a Rotozip or Dremel Advantage. My use will include cutting wallboard and cut off saw. These are appealing to me because both are available with a plunge router attachment and flex shaft .I don't believe the dremel has a cut off saw like the "zip" for Rotozip. I'm not a "heavy" user, but additional functions of router, circle cutting , etc. would be "nice to have".
Any advice re advantages of one vs the other? Appreciate any input you're willing to provide.
Happy Holidays
