But I gotta say... all those extra connections can create problems in your signal path.

You pretty much have to have those same connections either way (unless you have to add extra adapters to do the split). Only difference with a channel insert is that one jack carries both the preamp output and the return rather than having a cable from a standalone pre to your interface and a separate cable from the interface out to a channel input on your mixer for output. And of course, you don't -have- to use the mixer for output. I don't. Two outputs of one of my interfaces go directly to my speakers.

Also, I must admit I'm skeptical about the quality of the pre-amps in a $100 Peavey mixer, but then again I shouldn't knock till I try it.
All I can compare it to is the gear I've used:
a Mackie CR-1604 (not VLZ), an M-Audio FW1814, a Presonus Firepod, and various random cassette decks over the years. The cassette decks always had high noise floors, so we'll ignore those entirely. The CR-1604 made everything muddy and boxy sounding. When I switched from that to the Peavey, the sound just came to life....
The Firepod sounds similar---I haven't really taken the time to A/B the two. The M-Audio FW1814 pres... I wasn't as impressed with them. The highs sounded a little brittle by comparison. They didn't sound bad, but they didn't sound as good as either the Firepod or the Peavey.

When I fist mic'd an acoustic guitar with my SP B1, ran it through that pre-amp into my recorder... I was totally blown away by the quality of the recording. So clean. It was miles ahead of anything i previously got with a dynamic mic.
Yeah. That's what a properly designed preamp will do. It's amazing how utterly lousy some cheap preamps sound---usually not because of the actual preamp (which may just be a chip in many cases), but rather because of cheap parts used to connect the preamp to the inputs/outputs.
Many a good preamp is ruined by poor quality filter caps to cut the phantom power out of the signal lines. Many a good preamp design is ruined by a bad power supply design that introduces hum or high frequency noise. Many a good preamp is ruined by somebody plugging a guitar cab's speaker output into it....
