Buttonhole, buttonhole, who ' s got the buttonhole?

We're looking for the perfect buttonholer. I have an older Bernina machine. I love it. I adore it. I wouldn't be without it. But it makes icky buttonholes. My second sewing machine, one from Montgomery Wards, made excellent buttonholes with an attachment. I let a friend borrow said attachment some years ago and haven't seen it since. I've also been chasing the perfect buttonhole since then!
Alas, the ultimate buttonholer is an elusive creature. It hasn't come knocking at my door and the internet seems to only sell machines on an industrial basis, and they're huge and expensive. I'm thinking I may have to suffer through buying a second sewing machine. Could it be? Oh the horror and the torture. Okay, I said that part for my husband. He doesn't "get" why I would want more machines. I have four already! (Two sergers, neither of which are plugged in right now, the Bernina, and an older Montgomery Ward machine that I keep around in case my friend returns my buttonhole attachment.)
All kidding aside, the buttonhole is an important detail on a lot of items. I'm making a wrap skirt for a friend and it requires two buttons. I have done everything but that. I guess I'm going to have to bite the bullet and make so-so (or is that sew-sew?) buttonholes on the skirt with the Bernina. Unless someone sends me the perfect buttonholer today.
Rounded, bar tacked, or keyholed - the buttonhole is a treasure.
