FWIW, Myth, I think I gotta echo PTP's thoughts on pay. When you've got a tight budget, obviously, you need to prioritize, cuz you can't spend money on everything you want.
One of Indietalk's regulars, M1cheal, is active in a community of actors/filmmakers who all volunteer their time on weekend projects with each other, and they are very productive. They have a track-record of working with each other, and the community has been well-established. In their situation, it makes sense to spend what meager budget they have on props, sets, etc., because it has been well-established that the volunteer cast/crew are committed to the project, and are going to show up when they say they will.
But if you don't have that solid network of talent in place, the commitment of your talent is a huge issue. I'd say it's pretty much normal for all near-zero-budget filmmakers to deal with talent that flakes out on the project, at the most inopportune times. With that in mind, if you've got any kind of budget, personally, I would think that talent should be priority #1. To use my own budget as an example, I had $5,000 to spend. $1,000 went to props and random expenditures (gas-money, PB&J sandwhiches), $1,000 went to my lone crew member, and $3,000 went to the lead actors. Of course, each of us producers has to figure out for ourselves what will work best, but I am definitely in the talent-first camp.
