AFAI remember the 9500 was one of the first G3 models Apple made back in '98/'99. They were equiped with IDE disks and SDRAM but they were quite good compared to the 8000 series.
This is a long time ago so don't take it as defacto knowledge.
I would say 100-150 euro for one of those in working condition. They were for MacOS 8.6 so usb support is somewhat shaky. should run 10.1 nicely tho'.
