Interface Help: Presonus or Focusrite..or?

[tracer03]

Okay, I'm tired of lugging my recording pc and sundry gear back and forth between my house and the (drummer's) rehearsal/recording house. That, and the fact that I have a few bucks squirreled away....

Background:
Home PC is a Quad-core, maxed RAM, Firewire and USB 2.0, etc. - so no system limitation.
Recording PC is a P4, also FW and USB 2.0.
Currently using a Presonus FP10 at aforementioned rehearsal house.
DAW: Reaper
Signal/fx: Sans Amp Para Driver + fx

Difficulty: ~$100 (or less, if possible).

I have my eye on a Focusrite Scarlett 2i2 (on CL locally). Or a Presonus Firebox (here in the classifieds). I've heard great things about it, but I'm also familiar with Presonus gear.

I'm looking for something small I can hook up to the home PC when the mood strikes, or if I want to layer parts at home. Just looking for something with 2in, decent pres and recording quality.

Thoughts? Any other suggestions (about the gear, that is...)?

Help of any kind is welcomed - thanks in advance.

I'm sold on my Firestudio Mobile and the quality of the recordings. The unit is small, lightweight, doesn't heat up, and it works flawlessly. If I were you, I'd get the Firebox of the 2 choices you listed.
