Anyone ever played with this frame? I'm looking to pick one up but still not really sure on the quality of Yamaha's racquets. It's from the 90's I believe.

I wouldn't worry about the workmanship of Yamaha frames -- it's pretty exceptional. For this reason, the secondary parts of their 80s and 90s frames tend to hold up very well, such as the grommets, butt caps, and grip bases. That said, the EOS line was, for back then, a LIGHTER performance alternative to their standard weight Secret models. I knew a very good player who swore by the 100 model and could have easily wielded a heavier bat.

I agree about the workmanship. In high school (early 80's) I recall saving up money for a Yamaha YFG 50...one of the best racquets ever made. It makes me wonder why Yamama ever left the racquet making business.

Someone told me they got in a patent dispute with Wilson. Something like that...
What's the current "market price" of the EOS?

Ah, it's tough to get grommets for those Yamahas now days. But I have one in my sights. 50 bucks.. good deal?

Ahh. Pretty expensive prices there.
I think the Yamaha racquets were high quality. The EOS I like somewhat less than the others, since it's "Efficiency of Swingweight" design means a light, relatively head-heavy racquet (in the spirit of the Wilson Hammer) but with the stiffness of the other Yamaha Secret racquets. (Ouch).
There was another thread about the EOS a while back: http://tt.tennis-warehouse.com/showthread.php?t=339707

Yamaha made racket and ski, but gave up it in 1997.

My wife played with this racquet, and love it. At the time it was the lightest racquet that still had aspects of a "player's" frame (reasonable head size, stability, not overpowered).
The way I heard it was that Wilson sued Yamaha, claiming that their "Efficiency of Swing" [EOS] technology infringed on their patent for their "Hammer" technology.
Yamaha decided it had too many other businesses to worry about lawsuits, even though this suit should have been easy to fight. (Where is the patent idea in a lightweight graphite frame?) It totally left the tennis racquet business, including discontinuing its fairly popular "Secret" models.

I assume it's akin to the idea of patenting weights on the perimeter of the hoop (at 9 and 3)?

They also had a lawsuit on their hands with the Secret rackets. Kuebler claimed that their Resonanz patent was violated by Yamaha in the Secret frames. Wilson's lawsuit may just have been to much for them and maybe that's why they quit making rackets overall.
A pitty though, remember their YWG 99 Image.....Nothing less than a piece of art.
I've got one on the big auction site.

I'll never forget when I got my EOS 100 in '91. To me it was a revelation in racquet technology. Light but slightly head heavy, very stiff with zero vibration. Not as stiff as the Secret 04 hammer but an incredible racquet. Stole out of my front seat 3 weeks later in my buddies driveway. I just bought another one 32 years later and can't wait to string it up with some poly and let it rip. Yamaha was at the forefront of racket technology but didn't want to get into it with Wilson so they left. Small biz for them anyway. Can't wait to get my EOS back!
That is not the original EOS. The EOS is a 100 or 110 sq. in. in a kinda ugly glossy brown and grey finish.

Both are EOS! Same mold two versions: The grey EOS (Graphite, Singapur) and the blue EOS RZ (Graphite/Fiberglas, Taiwan, cheaper and heavier than EOS).
