When you spring for a Church I recommend spending a bit extra and getting the ST-9100 (or the much smaller Ugly if you don't mind dealing with 2 small level controls instead of 1 easily adjusted large one).
Chris says the ST-9000 is a good pre too and I'm sure it is, but the ST-9000 won't provide attenuation so is not as versatile.
According to a previous post by 3-Fan:
The 9000 knob is not a gain control, it is only an output control. So even if you have the switch to the +10db setting an the knob at something other than full, the recorder is still going to see the internal gain structure of the full +10db. For instance, if you wanted say +15db, you could set the preamp to +30 and use the knob to attenuate back to +15db but your internal gain structure would still be +30. You aren't changing the gain of the preamp so the input could very easily overload. I learned this the hard way!!
The ST-9000 does provide up to 30 DB of gain instead of the 20 provided by the ST-9100, but you already have the FEL for when you need a lot of gain.
