Thank you all for your help!
I think i have more than i asked for.Now it’s time for me to make decisions, but i can gather enough info from this thread to make them.
The budget will not grow, that’s for sure, the problem is that if a don’t spend it this year, i’m not sure if i will have more next year.
I think i will definately have to go with a “home-made” pole, and maybe spend more money in the microphone.
Nobody suggested the digital recorder that i was thinkig of, instead, everyone proposed to record directly in the camera (wich has a mini-jack input for audio). I guess it’s a good way to save some money.
Thanks for the effort. If one thing i learned from this thread, it is that 500$ maybe a short budget in order to get a good quality audio kit for video production.
Anyway, as i said, very instructive thread for me ! Thanks!
