There doesn't seem to be many low priced 2-channel portable preamps to choose from.
Juicedlink seems to be the only releasing several types that also reasonably priced and not too large.
As it is, recorders like the Tascam DR-60, particularly at present B&H prices, seem to be a choice that unite preamp and recorder.
Busman seems to provide a preamp upgrade for it, which would still put the unit below Sound Devices prices.
Cons against the DR60, from what I have been following, are the hum loop and the XLR sockets, which seem to unrelease certain XLR connectors.
