I use the Naniwa lapping plate, it does the job just fine. It's about a third of a size of a normal stone so you gotta do figure 8s. Remember to lap before you hone, not after (changes in ambient temperature and humidity cause resin based stones warp ever so slightly - nothing you can see with your eyes but lapping before honing will mitigate the issue completely)
Some people prefer a DMT plate for lapping. It's good, but too coarse when new and needs to be worn out with screw drivers or other tools. I didn't want to mess with it and chose Naniwa lapping stone instead.
