Well, anyway, your post is full of logical fallacies, yet you couldn't even answer Oldkoot's simple question. Facts were presented, but none by you. You chose to bash and insult.
Oh please, must we have another one of these threads? Is this sort of comment helpful to the OP?
In a sense, yes, because the OP knows he's gonna get biased answers and fanboy flag waving.
One thing you can do is look at the finds people are posting, and the machine they are using. If you see one machine consistently posting more and better finds of the sort of targets _you_ wish to find, then that is a checkmark for that machine. Of course, its not that simple, as perhaps more people use machine X than Y, just because it has been around longer. But it is something _you_ can observe while ignoring this sort of negative fanboy chatter. (It is one thing I did when choosing between the E-Trac and V3 back in the day; I watched posters I felt were honest and credible, and just tracked their finds on silver coins, which is the primary target _I_ am interested in).
I've been reading this forum a long time. There are simply posters, in this thread, in the recent past, and the distant past, who I still have no clue what they actually find with their machines. I think that's important. They seem so smart about this and that, but this is actually a humbling hobby. Show me the actual finds. Me, a summary of every find I care about with my E-Trac is in my sig, even if I rarely post this rosie or that.
Another thing you can do, if you can swing it financially and hassle-wise, is buy one machine, see if you like it, and then you are done. If you don't like it, buy the next machine on your list and compare. Then you sell the machine you don't like. You lose $100 or so and some shipping hassles on the losing machine. I also did this with the V3 and E-Trac, but was lucky enough to be able to own both machines at once and compare them side to side, knowing that I was over-budget temporarily, but I would sell the loser and be back under budget at the end of the day.
If you get 17 years out of the winning machine, as you did with your White's, the hassles of this approach will be forgotten in the long term. I've gotten 12 years or so out of my E-Trac, and never looked back on the small loss I took on the V3.
The beauty of this approach, tho a bit more financially awkward, is it allows you to find the machine _you_ are most happy with, while avoiding the fanboy fights that distort objectivity.
At the end of the day, while a good machine is very important, getting on good sites is probably more important. If you have limited time, spend in on research and permissions, not fanboy debates. If made in America is important to you, there are posters on this forum that find mountains of silvers with Garrett machines (I don't know Garrett, so I can't name the model they use).
I won't comment much on machines I have not used, but I will say this on ones I have. I find the Nox has poor build quality. If I buy a machine, I do not want to buy aftermarket parts on top of it, but if that doesn't bother you, then fine. I also find the Nox has worse target ID and more iron falsing vs the E-Trac on deep potential silver targets. JMHO in my dirt, and I am a one trick pony trying to find silvers efficiently.
I find the Deus II (which even used, may still be out of your budget) better at iron falsing than the Nox. But I find the TID range on high conductors too limited compared to other machines. I also find the charging of the Deus II more of a hassle (specifically the limited life of the coil charge) than I would prefer.
If you are looking for silver coins primarily, a used E-Trac is well in your budget. The negatives are weight and ergonomics, and it cannot really be used in the rain or wet sand.
HTH and trying to be objective. Good luck.
