I'm making a teak mirror frame for a bathroom vanity area. The top rail will be slightly curved (think torri gate). I own neither a band saw or scroll saw and was considering using my Porter Cable hand held jig saw to make the cut. I'm guessing this would leave a ragged cut that would require lots of sanding. I'm now asking myself if this is a good time to invest in a band saw or scroll saw. I buy dimensional lumber so don't have a need to resaw (this could change I suppose). I don't do any crafts stuff (toys, etc.) so don't need really tight curved cuts (but might want to make a furniture piece some day that requires a tight curve). I've read that the band saw is preferred if you're making long cuts through thick or hard stock...such as 4/4/teak. Not sure if this is true.

This is probably a common decision for woodworkers. Any comments appreciated.

Thanks
