I like those a lot, but only with the cover option. Definitely worth a little extra money for a cover if it does not come with one already.
The junkyards have lots of them too. On '88 to '98 GM trucksl there is a buss-bar type with 5 studs on a common rail. No cover, but it's got a big "shield" wall to keep things from touching accidentally.
Ford has a nice single/double stud style I like a lot too. They are independent studs of two sizes, but often can be found with an interconnect/bussbar installed as well to make it common stud. Surrounded by a wall with slots for wires, it's pretty small, tidy and "factory" looking.
Good luck. Lots of stuff out there, including just single studs from the suppliers like Waytek Wire and others. Usually no caps or covers though, so in my mind they're less desirable. But still functional and very small footprint.
