OK, Thank you very much. In meantime, I got enough of informations for my decision. I am planning to buy the next configuration:

- Kurzweil K2500
- KDFX Board
- Piano, Orchestral & Contemporary Sound Blocks
- 128MB Sample Ram
- Some internal HDD or external SCSI CD-ROM

I have just a few questions more about this.

1. I read somewhere that K2500 accepts all MAC-compatible SIMMs. Are there some incompatible models of this memory? Can I use the 72pin SIMMs from PC?

2. Is the resonable to buy only external SCSI CD-ROM instead of HDD, for saving money? How quick is loading of entire 128MB from CD-ROM?

3. When I buy some sample CDs, can I combine my favourite programs from disks and my own-made programs and record this compilation with my CD Writer on ONE CD-ROM disk, then load into the K2500 before the performance?

4. Can I configure K2500's Portamento so I can hear the gliss ONLY when I play legato (not every note)?

5. Can I find contents of the Sound Blocks (Piano, Contemporary, Orchestral) on some CD-ROMs? Must I buy these modules (instead of CDs), if I want to have it's samples?

6. Is the Fan Kit included in all newer YoungChang-made K2500s ?
