CloneCd and Waitec T-REX (EIDE) probs?

I was about to buy a Waitec T-Rex (EIDE) and using it with CloneCD.
I saw from Hardware requirements that T-Rex should be a great choice (RAW DAO 96 etc etc).
But when I checked an online Forum (other than this one) I saw one posting about a guy having lots troubles with T-rex (eide) and CloneCD…about subchannels too…
I know (from CloneCD hardware reqs) that I should update firmware of T-Rex to 5.32 (already downloaded it from waitec BTW).
Anyone knows about troubles (REAL) with T-Rex??!?!
Help me please, I am stuck here and I am not sure about buying T-rex or not. :frowning:
