The Danelectro cool cat drive is supposed to be a near copy of the OCD:-
you wouldn't use the meat knife on crusty bread but, equally, the serrated knife and straight edge knife aren't going to go through raw meat as quickly
not suggesting you should go for it though, just putting this in as an incidental anecdote.
Get the Cool Cat Drive - I have one and an OCD v.2 and there is practically no difference between the two = different pots mean the settings are exactly equivalent and the OCD is slightly clearer - but its not a £100 difference
