There are a few I can think of. Avery is not listed and I think they're still in production, as is Bosworth. Carnelian made a racket called the Pro Tour Graphite. Feather made a Classic Pro and a CourtTi 2000. I don't see MegaAge, and I think they are based right there in Australia. There's a Natural Power Grip racket. PowerAngle is still made. Technifibre's are still available, as are Vantage rackets. Another one listed in the USRSA book is Winjammer and X-45. X-45 are tilted head models similar to the Ergonom.
With a little work, you'll be to 100 in no time.
