Handles for an ASC12?

I recently got an ASM 12 and love it! But what I don't really care for is the handle placement. Seems like it would be better to have 2 side handles to make it less awkward to carry. I'd hate to drill into it and install my own handles, but I think that's what I'm going to do. I gig most every weekend and it would make loading in and out much easier.

So I guess my next question is: Where can I buy the matching handles? And is this a bad idea as far as resale?

Thanks
