True, but that basic PPE as described above is much cheaper, few hundred at most, typically around 200 including farm call. You can get stuck with things like developing cataracts too small to easily see, breathing problems, heart murmurs, small gait irregularities that will eventually developed into lamness, subtle signs of chronic illness, like Cushings, that will require medication. Stuff like that even experienced horsemen miss.
To me it’s worth it plus, if you use your vet, they get a base and have the file started before an emergency and can pull a new Coggins, maybe a fecal to see where they are, possibly vaccinate if they are not up to date. Cost a couple bucks more but then it’s done and you know where they are and what you need to do management wise-cheap horses generally have not enjoyed the best in vet and farrier care and most need to get on that track sooner then later.
I only bought one horse anybody else wanted, most were pretty cheap but I found just that basic saved me a ton of mistakes that went on to be somebody else’s mistake costing far more then that basic PPE.
