Suggestion for buying a 5.25 drive

[anormal]

hi,
i can buy these drives from a user in a forum

Teac FD-55GFR 7193-U
Teac FD-55GFR 149-U
Teac FD-55GFR 190-U
Mitsumi D509v5
Mitsubishi mf504c-315M
Chinon fr506

I am going to use with SCP and with kryoflux, for imaging and copying,

In your experience (or other users), do you suggest me a pair to these?, it seems 55FGR don't support weak bits (as i read in the thread), appart from that?

thanks!!
