Well I waited for that cheap DR-07 to materialise, but it didn't happen. Realistically, I was looking at £120 for a new one. Then you have to think, why not get the DR-08? It's only a bit more, and you get 24/96..mmm. £160 is not that much.
And then I remember that I love cheap, so I snapped up an iRiver H120. £46 on ebay! You can't argue with 46 quid.
I'm quite suprised and very happy because using external mics gives a pretty OK result. Good enough for now. Certainly comparable to HiMD recorders, entry level DATs, my old DCC and the like from back in the day.
I remember once I soldered my line out straight onto the Vo of a sound card's dac chip, and dramatically reduced the interference being added by the card's mixer. Might try something like that on the iRiver to get the cleanest possible line in. The great thing is, I can hack around with Rockbox, SSD drives and iPod batteries without risking much money.
Personally I think a great solid state recorder should be < £100, so I'll carry on waiting and use the iRiver in the mean time.
PS: Thanks for the replies.
