Well I can't completely agree with all the above, I understand the thinking. We all will have an opinion and rarely will most have the same opinion.
I've had most of my machines for a couple years. Before the mojave came along there was (and still is) the compadre. My dirt is mild.
Funny part is, with all the detectors I own, when putting around or tot lot hunting, I always grabbed my compadre.
I have the vaquero, and it's a great machine.
But I still am more likely to grab the mojave or Compadre. They're just simple and great performing.
Don't get me wrong, I still hunt with my modded Cibola, vaquero, bandido II micromax, and my Deleon alot. But there's something about the compadre (in my soil) and the Mojave that just makes me smile to use them.
The reason I don't have the silver is because I have the cutlass umax. Not to be confused with the cutlass II micromax that preceded the silver. Mine is essentially a silver umax but operated at the "magic" 12khz, has sensitivity knob, and kick down all metal (like the vaquero's click down on disc knob), and has the higher freq audio like my Bandido II Micromax. This machine was only produced for 1.5 years before they changed to the cutlass II micromax at 10khz.
To be honest I got it instead of modding a compadre, but now that the Mojave is here it's actually easier to say it's a mojace without the ground switch. It was purchased before the mojave was available.
So I don't have anything against the silver, but for the cost, ground switch and the 12khz I still say Mojave is a better buy right now than the silver. But that's without ever using the silver, just going on specs and what I know about my 10khz vs 12 khz machines.
If you were only going to buy one machine and could afford it, I can see going for the vaquero.
But given what you've stated, the mojave is a great buy and even if you don't get into the hobby you aren't out much money. You won't be disappointed with the mojave.
Also, later if you get a more expensive machine, the Mojave can be what you let others use when they are interested and want to hunt with you. It's dead simple to use. But even then, you'll still use it I'm sure.
