MY WEIGH MBSC-50 is the scale I just ordered. I got mine from a guy on eBay for much less than what you see at many of the stores online. I think it's a nice setup and I like that you can use it for other things too once the puppy days are over.
I have planned on getting my "kit" piecemill and bypassing some of the little stuff that you already have around the house (since I'm a pharmacy technician I seem to have gathered some of these items inadvertantly).
