Second-hand study guides

[CraigV]

Hi All,

Might be a weird question, but is there any place I can get second-hand study guides for the track to MASE Servers & Storage?
I was an ASE in servers, and a MASE in storage and ended up having to let my certifications expire, and not by choice. I'd like to self-study them again, but the books are very expensive when converting to our local currency. So, trying a long shot here. If I have to buy them new, then I'll have to stagger them.

Thanks!
