Digital BW, The Print

I’d like to buy an R1400 and experiment with QTR and Eb6, BO, HP-PK, etc. perhaps moving to a CIS when I settle on something.  What are the recommended refillable carts I should look at for the 1400?  Are the Lin Exports carts on eBay any good? http://tinyurl.com/mqgctm

Thanks for any advice.
