I’ve been looking to find a reel that can serve as an inshore reel here in the Northeast for stripers bluefish black sea bass stuff like that while also being a solid bass reel. I’m on somewhat of a budget ~$100ish. Found a lightly used Curado 200K for $100 on eBay. Should I go with that or go for a new Penn Squall 200, designed specifically for saltwater? Any thoughts? 

Curado 200 is good, you cant find better option.

Lew's still has a sale price of $144 shipped for Super Duty G. 

I've been fishing one in the salt for four years and added a second. 

Spool capacity on the Super Duty G is between capacity of Penn Squall 200 and 300.

Super Duty G has 6 more ball bearings, the main difference will be double worm gear BB and better pinion support with a spindle cap BB (plus double handle bearings). 

Squall has a very Doyo look about it, so I would say they're very similar reels - the schematics look nearly identical. 

Lew's website even has a FAQ about saltwater, and they rate the reel salt suitable. 

Slight difference in the drag rating, but not enough to matter. 

 

#1 inshore reel down here is Shimano's Citica. 

1st generation revo inshores are solid and easy on the wallet these days
