For around $200 you can get an IAC Hawk from CTD:
I'm not sure you can do much better than that. It's a Remington 870 copy with a Picatinny rail for an optic, 5 round magazine capacity, and matte finish.
I'd save some more coin and get a real Remington 870 Police Magnum or Mossberg 590A1.
If you just don't feel like spending much on a pump, then the IAC Hawk is about as good as you're going to do. There are other proprietary and 870 or 590 clone foreign manufacture shotguns available for similar prices, but the Chinese make a decent 870 copy.
You haven't told us what you want to do with your shotgun, so I don't know what you intend to use it for.
I would not buy a single or double for home defense, but for hunting either of those will be fine.
Most dirt cheap pumps are for home defense, not killing Bambi or Daffy. That said, low cost pumps or replacement barrels with chokes suitable for fowling are available.
For HD, a pump or semi-auto will work. Reliable semi-autos suitable for HD work are not cheap.
A Remington 870 Police Magnum or Mossberg 590A1 are both around $500-$600, depending on the model and who you buy it from. Yes, you can sometimes find them for better prices, but I'm talking general retail prices, not discount or special prices. Neither is materially "better" than the other, both have slightly different feature sets and perform the same job quite well. If you live in a humid environment or near an ocean, you might want to consider the marine models of the aforementioned shotguns.
