Are there any significant differences that would make the $200+ premium for a H4n worth it, compared to a $100 H4? (Used) My primary use for now will be recording live music. (I know a few musicians)
If you want to use it to sync to video then I wouldn't suggest it - some members have reported audio drift issues with the H4, while the H4n doesn't seem to have those same issues.
Granted - you can always retime your audio to sync up - but personally if I planned on using it for video I'd rather spend $200 not to have to do that everytime.
I have an H4 and have not experienced drift with clips of 5:00 duration with my 7D or HV20. YMMV. I I hear the interface is improved, that alone might be worth the premium.
I don't have any video equipment anyhow. (Yet) I wouldn't do shots any longer than a few minutes (If that) and I really don't want to pay $400 for a recorder just yet. Being in high school, my income is minimal. I'll just get this H4 and see what happens, worst case I can probably sell it at cost or maybe a small profit.
