I am on a low $650 budget and want to upgrade my current gear. I need it to record sounds for films, documentary etc... The user reviews on BnH are very mixed that its hard to decide. I need something that will provide good sound but very low to little noise as my current gear (Zoom H4N and Tascam Dr-40) doesn't provide the cleanest results.
Here are my options:
1) Tascam DR-70D 2) Tascam DR-60DmkII 3) Tascam DR-680MKII 4) Tascam HD-P2 Portable Stereo CF Recorder
Which of the 4 is a good investment?
