I'm surprised nobody has mentioned an Abloy PL362 with Protec core. That's tough and nearly impossible to pick. (The throat width is approx. 30mm) $215 US new
Here is an 833c next to a PL362 next to a No3

There is also the ABUS Rock 83/80 which is massive, but the drawback is that too often it is sold with a Schlage SC1 or Kwikset KW1 keyway, so you would have to request an ABUS core, but that's still pretty easy to pick. $105 US new
Mul-T-Lock #13 C-Series 1/2" shackle with shackle protector is also a nice choice. (throat width is approx. 32mm without protector, 26mm with shackle protector (shroud) $110 US new.
good luck,
