Oil vacuum gauge: permanent one good idea? Also are all de-aerators equal?

Thinking of getting my new de-aerator with an integral vacuum gauge that some of them come with, or, if I don't, installing one inline, but I think I've read that a permanent gauge can be an extra possible spill point in case it blows, or gets knocked hard. If that's true I don't want one. I do have a Westwood T15 supply line vacuum gauge setup that I haven't used yet and don't know how to, but I thought a permanent one would eliminate disconnecting a flare fitting now and then.

Also interested in any opinions on de-aerators. Tigerloops are everywhere but I've been looking at MITCO (made in USA, I think, has an integral shutoff valve that I like, but product seems hard to get), anyone use anything besides TL's, any real differences? Can't use Sid Harvey's because they won't sell to non-contractors. I like the ones that have an integral shutoff valve, because I'd rather not use the Firomatic as a shutoff although I guess most people do.
