Brother: DCP1610W vs DCP-1612W vs DCPL2620DW

Anyone have experience with any of these printers?

• DCP-1610W
• DCP-1612W
• DCPL-2620DW

Brother Spain had recommended the DCP1610W as best bang-for-the-buck. But on Amazon.es I also was recommended these other two models. Looking for a new mono laser without the bells and whistles. Doesn't have to be a multi-function but it would be a bonus.
