I have an old Milwaukee Super Hole Shooter that I haven't used in years. Looking up your drill motor reminded me of that old thing. I keep it partly because I am a "tool whore", and partly because if you need to drill some big 'ol gnarly holes, that will be the drill to do it with! Yours would be good for mixing things like drywall mud, mortar...things like that, and also for landscaping or carpentry work if you need to bore a hole through a railroad tie or an 8X8 post. If you don't think you need that...sell it and put the money toward something that you will use or get enjoyment out of.
Like I said, I'm a bit of a tool whore, so I have a hard time parting with stuff, and it seems like nearly every time I do, a few months later, I could have used it for some project I am working on. This is also why I have no room in my garage!
Just my $.02
