The absolute best crosssdraw for the N-frame is the Sparks HSR. Can be had vertical for EITHER side, or crossdraw for weakside carry in true crossdraw. Very compact, and well designed, and can be ordered for any belt size. I tried a Kramer for the N-frame, but it was a bit bulkier, and needed a longer length of belt to be mounted, and thus interfered with the belt loops more than the Sparks. The Bianchi Cyclone is a good crossdraw, but I think it is out of production, although you can sometimes shake one up on ebay.
