Actually just got an answer on it I think, the person I got them from says they are the RN-4081, although I'm at a loss on how the carts are supposed to fit from looking at the pics LOL
Edit: it's the DSE 103, but the RN 4081 will work
Edit Edit: it could be the other way around, I posted on TW's forum to get an answer, I'm all for trying out new models, just not all about paying 13 dollars PER atty
