I'm no Bill O'Reilly, I'm not a conservative compared to most people, but when it comes to some things, like mics, I'd go for what I'd call "standard classic vocal mics". I'd start there. The SM57 is and I own two and still can't figure out what to use them for except singing Creedence at gigs.
You know some studio classic don't cost an arm and a leg. The Sennheiser 421 (used on my 1st 2 releases, found it hard sounding), 441's (I have two 441's and find them hard sounding too, not for me for recording, but I use it for live gigs and love it) are standards. The RE20 and SM7 are classics. Those are both large diaphragm dynamics. You probably want a large diaphragm condenser though for the high end.
The AKG 414 is a classic too. Lots more. For whatever reason, AKG's never connected with me, but they did with lots of people.
That's playing-it-safe me, I'd start with the cheapest classics and go from there. I don't know much about the new $49 Neumanns from Hyundai (sorry for the sarcasim) but even those I wouldn't rule out because I've bought a lot of cars and I'm never turned off by a low price - it could be a deal.
But spending $800 on a pre if you're using $300 mics is bonkers to me. That's too much money towards a U87. There were two that went for $1600 recently and one here for $1400:

If you got the $800, save another $600 for a $1600 Neumann. My Neumanns are worth WAY more than what I paid for them so actually they are, in the end,
the cheapest mics if you can believe it.
I'll bet could've bought that U87 for $1600, used it for a year and sold it on this forum and made a few hundred.
You really can do almost anything, even with no money, if you figure out the angle.
