>>6668309 said, Sinanju is excellent. While all the base Sinanju RDs are the same, you'll want to pick up the Animation Edit. version (RD number 155). It has more accurate colors to the OVA and more accessories from specific OVA scenes.
One thing to keep in mind; there is going to be another release of the Sinanju, which is effectively the same as the Animation Edit. but with added tampo detail (Katoki style). May want to wait for that if you want those added details.
