You wouldnt want to buy a Stagea as an outright performance car, they are quite heavy and dynamically they arent that flash. I've got Tein HAs in mine and even with them it leaves a little to be desired. Straight line speed is about on par with an R33 GTSt of the same Spec. As a family car they rock, plenty of space, big doors, good aircon.
In terms of price you'd be real lucky to get one much under 40 regardless of year due to the fact that no-one has compliance under the old scheme. Mine is for sale as it appeared in SPEED for around 50k - bear in mind its the only fully registered Stagea in the country.
