I'm still using my Zoom H4 but plan to go for a proper field recorder sometime in the next
6-12 months.
The H4 is good though the preapms are noisy at medium and high
gain settings, though I gather this has been much improved with the H4n which is also far
eaiser to use. As a versatile hand held recorder the H4n is hard to beat... If you want
XLRs with phantom power, I believe it's the only handheld available with that feature.
I use the Rycote mini windjammer with mine...

It cost about £25-30 IIRC and as a bonus
it fits fairly nicely (if a little loose) on my Rode NT3... You wouldn't use it in a gale
but it's made a big improvement over the foam windsheild (which the Rycote is placed over)
that comes with the H4 as standard so it's well worth the money. I consider it an
essential accessory now I know how good they are.
From what I have read, the
Fostex FR2 does seem rather popular with sound recordists. Hopefully though, when I
upgrade, I'll be going down the Sound Devices route... But I'll always carry the H4 as a
stand by.
