I started with a Harbor Freight #4 which is now a dedicated scrub plane. It isn't fit for much else, sole was nowhere near flat, chip breaker was messed up, blade couldn't hold a decent edge, etc. I only might recommend it for someone afraid of catastrophically messing up restoring a vintage plane. I have a WoodRiver 5 1/2 and have no issues with it, I actually don't remember the last time I sharpened. I also have a set of forstner bits from WoodRiver and they are hit and miss. One bit cuts like butter and another is a pain in the butt.I'd rather buy Harbor Freight than WoodRiver. 😉 Jokes aside, my lack of confidence in WoodRiver stems from to two sets of forstner bits that would not cut AT ALL. Horrible product. I switched to Fisch Wavecutters and they are amazing (albeit 3 times the money). In fairness, I do have a WoodRiver round scraper that seems OK.
On the flip side, I have many other Harbor Freight items including my lathe which works well.
