What are some opinions of multi-track recorders on the market.

I only plan to dump my 2 stereo tracks into input 1 and 2.

I might add some more vocal tracks.

I'd like the ease of an onboard burner.

Is there a huge sacrifice in quality on going with the less expensive units (BR900, Tascam DP-02) vs the larger VS-1824, D1600, etc?

Suggestions appreciated.
