Which SANDER all rounder?

I have a Skill Octo. It has several different attachments that definitely help with getting into grooves, etc, but it still doesn't get tight corners, etc. I am on my second one in 5 months, so I'm not sure if it is the best on the market, but the attachments are really helpful! I got it at Lowe's and when my first one broke (one of the parts that hold the attachments on) they exchanged it with no problem! I don't know what to compare it to because I've only owned one sander, but I'd say it vibrates at a 5 or 6 on a scale of 1 to 10. Good luck!
