Taprite makes decent ones.
Do you mean dual body (two separate pressures) or just one body with a splitter?
If you only have 2 kegs and don't want any more, the dual body regulator will work fine. You can even use a single regulator with a cheap plastic T in there, if you don't mind running both kegs at the same pressure. But I'd grab the dual, that'll let you run two different carb levels.
