HD PCB Archive. Advice for the purchase

[Astra5]

Hi. I have just started the activity of data recovery.
Now i am in need of PCB for diagnosis and recovery.
THE idea would be to create archives always ready to use.

I found this site where they sell pcb: http://www.drivestar.biz/hdd-pcb-c-65.html

Also interesting are the motor-chip.

Recommended the purchase?
OR i can find a better?
Thanks
