Kumho ECSTA Supra 712 Tires?

[J]

  Hello everyone!

   I was wondering if anyone has had any experience
with these tires?  I was cruising tirerack.com for
some new rims and summer tires to put on my 1996 200sx
SE-R; and I came across these?  I was shocked at the
cheaper price (compared to the Goodyear Eagle RS's, I
had on the car!!) and was wondering if they are worth
every penny plus more($64-USA)??  Thank you for your
responses in advance.  Also, if you wouldn't recommend
these tires, what would you recommend in the
high-performance to ultra-high performance summer
195/55-15 size?
