There are lots of good ways to divide up your budget, depending on what would best serve your needs.
For instance, the Marshall V67M is available from Mars Music for less than $110 delivered. It's an incredibly good single-pattern vocal mic, but comes with only a stand adaptor for that price.
With the difference, you can get a great, neutral preamp like the single channel Grace Design 101 (Soundpure is offering it on Ebay for $549 plus $18 shipping, for instance), or -- to go for a full vocal processor with distinctive, adjustable coloration -- you could get the single-channel JoeMeek VC1Qcs for about $10 more from the same place. And, just to make your choices a little more complicated and enticing, they have justed started offering the 2-channel version of the JoeMeek, the new TwinQ as it's called, for about $750 plus shipping. All of these are within striking distance of your $800 with the V67M.
You could also move up to the outstanding, multi-pattern
Studio Projects C-3 microphone at $349 with shock mount and aluminum flight case (different vendor, but also on Ebay right now, and free shipping), and attain another whole level of openness and quality in your mic. It's a big step up from the C-1.
At that price point, you'd have enough left over to buy the well-regarded M-Audio DMP3 2-channel mic preamp for about $250 AND the oustanding FMR RNC ("Really Nice Compressor"), which sells for $175 delivered, also on Ebay right now.
There's yet more to consider, though. (You really do have a rich abundance of choices that simply weren't available a few years ago at this price-point.) Sometime in the next few weeks, Studio Projects is planning to introduce its "B" line of microphones. The one you might consider (as a possible alternative to the C-3) will be their new tubed mic, complete with power supply, shock mount, connecting cable and flight case, for about $350.
If that isn't tempting enough, the Rode NTK tube mic package is available for about $450 on line, leaving enough for the DMP3 or a JoeMeek VC6Q with enough left over to buy the Marshall V67M as well.
And, with the "B" series coming shortly, you can already buy Studio Projects' incredible top-of-the-line T-3 tube microphone package for $599 on eBay right now, leaving you about $50 short of the DMP3, but close!
The point is, you've got enough in your budget to move up into some seriously great sounds, and no matter how you divide it up, you're probably going to be very happy with what you get.
If I had to choose right this moment, I'd probably go for either the new
JoeMeek TwinQ (looking forward to needing/wanting two channels of vocal processing in the future) and saving a little more to buy the inexpensive but very good V67M from Mars Music in the short-run, or I would go with the C-3 ($349), DMP3 ($250), and FMR RNC ($175) and use the change to buy a mic stand or a decent mic cable.
Note that the prices and vendors I cite on Ebay are all authorized dealers with good reputations selling brand new equipment with warranties.
Other people will have different suggestions, and you should consider their recommendations carefully as well.
I'll be interested in finding out what you decide to get and how you like it.
Best wishes,
