Looking over the ins and out of the Tascam, it's not made for whole band recording. It's got 2 preamps, and 8 total channels to mix with. Not much to work with.

From what you described, you want computer recording, but you don't need Protools. Something along the lines of a Presonus FP10 for $300 has 8 preamps for 8 channel recording, and the software it comes with has over 40 channels to mix with. And it's probably as affordable as that Tascam was. And it comes with all the EQ compression and effects you need to get your "fuller" sound.

And I think the whole "Recorderman" set up is really blown out of proportion. Back when recording tracks were limited, engineers found ways to take 3 great mics in a perfectly tuned room, placed in the perfect spot, and make it sound awesome and fitting for that music era. 3 Behringers on cheap stands in a bedroom will get you 3 mics in a bedroom, not the "recorderman" sound.
