Edit: I totally misread what you were asking for, sorry! Ebay is your best bet, but I've had lots of trouble finding TCN modules. I was initially going to use TCN for the entire program but (a) I had a hard time finding TCN modules and (b) it turns out that the recommended reading was WAY cheaper than the modules that I did manage to find.
It worked out great because that lead me to completing the entire program using the recommended reading, which I actually ended up prefering to all other methods.
Oh well, maybe the link to the notes I sent you will be of some help.
