Thanks for all replies!
I've though about a good external mic but my preference at the moment is a ''all-in-one'' device.
I have taped more than 20 shows with my MD in the past just for fun. But to convert the concert on my computer takes some time.
One question about the internal mic's of the Zoom H1 or Tascam DR-05/07.
When recording from my shirt pocket, the mic's will be pointed to the roof and recorded the sound.
Will it also recorded the sound from people standing next to me?
I doubting about this because from what I've read the mic's will recorded the sound which you point at.
Personally, I think it's not worth bothering if you're not going to use external mics and just stick a budget recorder in a shirt pocket.
But if I were doing so, I'd make sure that budget recorder had omnidirectional mics - so that they wouldn't, as you note, be aimed at the ceiling. Omnis pick up sound from all sides equally; in a shirt pocket they'll obviously not pick up what's behind them (your body), but everything to the sides and in front.
I don't know how many recordings you've heard done with this method, but they generally sound like crap. PontiacB is an experienced taper and I don't doubt that he's gotten some decent recordings this way, but it's really a pretty bad method.
If cost is the issue, consider that if you want to have recordings at all, if you go to, say, 10 or 15 concerts a year, it's $10 a concert (or, the price of a couple beers) to have decent mics. If "convenience" is the issue, the better question is really whether you want to bother with taping at all. Nothing about taping is "convenient" and doing it right takes a bit of "sacrifice".
Just my $0.02.
