The best option, dollar wise, is the DMT325. The next best option, IMO, is the Atoma 400 (my choice), and finally the Shapton DGLP, which I have, but really don't use because I have the Atoma.
A DMT325 will do the job for you. An Atoma 400 will give a little more smooth surface and a more precise flat surface. A Shapton DGLP will give the more precise surface of an Atoma, but cost $379.00.
Try not to overthink it. They'll all work!! (Well, except for the Norton and Naniwa lapping stones IMHO) which I just don't use. Just how precise do you want to be and how much are you willing to spend?
