Yep, that Edirol R9 seems nice, but you must buy a SD card to record the show
...these IRiver already have a HD...I don't know about the IHp320 (some people here uses to tape, apparently no big differences in term of capacity/battery lenght), but the IHp120 is GREATTT
For the mics :
SP CMC-2 (AT831's)
SP CMC-4 (AT853's)
CA STC-11
MM HLSC-1
...all these stuffs are great and pretty tiny for stealthing...add a batt box and this is done.
Check in the "rig picture" forum, there are some pictures, then you will have a good idea of what your future rig will look like.
Then your wallet will decide for you
