I would recommend getting an Adaptec controller. Before someone screams, you can also get a Symbios/LSI controller or QLogic controller. All are well supported, but the Adaptec boards are easiest to find. You should get a controller that has the combination of connectors you need for whatever you're going to put on it. Some controllers, like the Adaptec 29160 have a SCSI-SCSI bridge chip that lets you put single ended and LVD devices on the same bus. The 29160 would probably fit your criteria -- it has an internal Ultra160 connector, an internal Ultra Wide connector, and an internal 50-pin connector. The only caveat about the Adaptec boards right now is that the Ultra160 controllers will only run at 80MB/sec with 4.0 or -current. You need Justin's patches that he posted to the -scsi list a couple of weeks ago in order to do Ultra160. Because of that, a Symbios/LSI controller or a QLogic controller might be better if you have to have Ultra160 right now. As for drives, I'd recommend high end Seagate and IBM drives. i.e. IBM Ultrastar and Seagate Cheetah and Barracuda.
