Yea, I have never heard of a SCD unit going bad, they are nearly indestructable, sort of like the saturns. I got the one I use now from an out door flee market in florida, so it sat in 100 degree, 100% humidity conditions until I bought it and it works fine.
edit:
I forgot to mention, if you plan on buying it with a genesis, you will probly want to test it before you buy, because used genni's tend to have messed up power sockets, and/or screwed up av outputs.
