Some BM Walmart has Brother MFC-L2690DW Monochrome Laser All-in-One Printer for $156 + Tax.
It does duplex printing, has wireless connectivity and comes with ADF for scanning.
Cheap replacement toner is available.
Big YMMV.

Some stores may have it at even lower price ($56).
I got 1 at my local WM for $156 + Tax. My older (~10years) Brother is still kicking with printing but scanning started to produce a yellow patch. Got it at ~$70 at staples — it was a refurbished printer. Replacement toner is bit more expensive than my older one.
Only deals, I have seen in recent time and at is price, are refurbished one.
