Do you want/need an
external one?
You can get an all in one box too like the fr2le or the marantz pmd 661 and just go mics right in to the onboard pres.
I have been for a few years and have no complaints.
However I am going to get a littlebox/biggerbox sooner than later.
For a few hundred you would be best to go there.
I have seen a few SD MP2's and SD MixPre's go recently for 350.
Another option which is less is an edirol ua5 modded or unmoded for cheap.
But with the littlebox being so customizable and NEW it makes sense to hit that in that price range.
Or again go for an all in one pre/ad/recorder.
I really dig the AKG/Apogee sound for mics ~> Pres combo.
Also there are a few on this board that run busman and or akg into a littlebox.
Will runs both akg's and busmans into a littlebox and also runs mics right into his fr2le recorder with its on-board pres.
Hit him up.
