Overdubbing or multitrack audio recording device with low latency

I only need about four tracks or an overdubbing feature, no effects, no equalizers. I want to record guitar/bass via DI and things like drum machines, so xlr and 1/4 inch jack will be used, 2-4 inputs are enough.

For example, the Zoom R12 looks basically suitable, but I have doubts that the latency when recording a side track or overdubbing and monitoring at the same time is low enough for me. Does anyone have any experience with the Zoom or recommendations for other devices for high quality and low latency recording? Maybe i will need a mixer and a seperate recording device?
