How hard do you want to work? You can do a lot with PVC. If your marching technique is up to par, something shoulder-ish and walk gently. 90% of quality video is rigging IMO. If you're indoors, you want a wide angle lens. You can only back up so far when a wall is involved. A wide angle also helps with low light performance and stabilization.
What I have is a Sanyo FH1 for video. Stabilization sucks, so a monopod and a spider brace mated with an ace bandage. (I'm cheap, not to imply cheap). And a couple $10-$15 clamp style work lights. A pack of $5 copy paper and a roll of $5 electrical tape for my green screen. I used the electrical tape because my transparent tape is too old to function, but it turns out that the stretchy electrical tape is almost ideal. Sticks well and is easily adjusted / removed.
For audio, I have Avenson STO-2 for a stereo pair. Run into some sound devices MM-1's (2x mono preamps). Run into
a Korg MR-1000. DIY shockmounts, DIY fake fur, and various other rigging. HQ cables. Most of which are new.
Total tally at todays-ish prices. $2,500K-ish in audio, and $500-ish in video. But little more than a soccer mom would have at $3K-ish. Which I guess would be the minimum. $100 monopod, $70 spider brace, $300 camcorder, $350 x2 preamps, $1,200 field recorder, $500 in mics, $200 in cables and accessories. And that's probably the lowball estimate of my current setup. As I crave mics nearly double or more of my current mics. Plus a camcorder nearly 5x's my current cams value. Just a hard compromise when I can get 5x of my current cam for multiple camera angles. Rig that up right and it's Imax (or as close as you can get on a budget).
