I just ordered an 8x3 DMT8C from SRD...it should be coming Friday/Saturday - it was less than $45...it should be worth it, as I have been using wet/dry sandpaper, and while it works, it is messy and somewhat time consuming. If I can cut the time and do the lapping in the sink with the water running, the convenience alone will pay for itself. And it will never need lapping itself (unlike the Norton flattening stone).
