If you are getting rain down your cuffs a fishing specific/wading jacket would be the way to go. Pretty sure every company has some sort of cuff system to keep water out. Most of them are rubber or neoprene cuffs, some are adjustable. Simms, Patagonia, Bare, Redington all have different jackets with varying price points. Check out their websites and see what you like and sometimes eBay has a good deal on clear outs or demo gear. Good luck!
Don't know if you picked up a pair yet but my vedders didnt last very long, about 45 days on the water after multiple patches. I ordered a new pair from DRYFT fishing. They are a relatively new company but they seem like they are built to last with double taped seams and reinforced knees and seat. 200$ plus shipping to canada is a little over your price point but nowhere near simms lol.
