this is more of a personal experience thing...not really a reccomendation.
I never spent a lot of time in the mic forum for a lot of the reasons you mentioned. Only if I wanted to get some peoples views of a certain mic - but I am fully aware that there is so much gear out there that I could never afford the time or money to track it all down and try it out - so I might as well just jump in and make some music at some point.
I've actually gathered up several of the hot topic mics over the past couple of years. I started with an SM57 and an SM58. The 57 I've found a lot more useful and like the sound of more even though they are supposedly the same thing +/- a pop filter.
Then I got a Rode NT3, loved it. A few months later scraped together the money for a second.
I was so impressed with Rode that my next purchase was an NTK. I didn't like it so much at first but I have now come to love it's lack of "hype" to the sound.
Got a studio projects C1 and it sounded great solo but I didn't like what it did for my mixes the more I used it, especially for lots of tracks in a mix.
Got all kinds of other things, an RE20, an AT Pro 25, Behringer ECM8000's (only 60 bucks for the pair...but probably the worst 'advice' I ever took. Not because it's a bad mic but because the way I was doing things and the room I was in I had no use for omnis. this is a great case of buying something that won't work for you just because everyone else is doing it.)
I have a couple of other things - and for me...at the end of the day I realized I was recording less and my tracks weren't as good as when I had only a few mics.
Somehow it was too overwhelming for me. When you don't have a lot of skills, the last thing you need is a big mic cabinet. When the best mic I had was an NT3...and I worked and worked with it to get the best out of all of my instruments...for me, it was more fun and more rewarding. Now there is the inclination to say "hmm..maybe that's the wrong mic."
I'm not saying I want to give away everything I have...just saying in some ways compiling more and more gear too quickly (in a project studio) is a curse and not a blessing. I've found this to be more true with mics than anything.
In terms of some more practical advice - I know I will never buy another "budget" mic again. I've tried out lots of mics of friends (mxls, ats, etc.) and have never been moved enough to say WOW! I have to have that one! It all starts having a similar sound after a while.
As I mature in the craft, and (hopefully) make more money at my day job, I am going to make "lifetime" purchases from now on. I'm not in any rush to do this because I am happy with what I have for now - at the same time, I am convinced that there isn't anything for a few hundred bucks more that could sway me away from the NT3s. But, KM184's on the other hand probably could...and the better and more classic the item, the better resale value it has if it ever came to that.
There are some mics that don't cost an arm and a leg but are still considered by many to be 'world class'...and I would be open to looking at those as well (such as the Dragonfly or Mouse - but Blue is kind of in it's own league in some ways).
What I am going on and on trying to say is that getting something that works for you is important. If you aspire for that world class sound - eventually you are going to have to pay the $$. If you are only after a level of sound which you get out of the first go-round - then more power to you...add it to your retirement account

You will (hopefully) become attached to the mics that help you express your art and no one could ever take them away from you.
For me that means that if I had Neumans, SoundDeluxe's, Earthworks...etc - my NT3's and NTK will still be in my cabinet. For someone else, maybe it's the C4's and T3.
