Someone who i recomend is a shop called briar paddocks! Very very good hhs even thothey are above 100 dollars but u also get a bridle, a brush, fake plastic food,a bag to carry ur hh and more!
There is also a shop called jarpol hobbyhorses and they have really nicely made hobbyhorses I even snatched one for myself and they are so good but it’s a bit darker that the photo. The hobbyhorses are kinda expensive in that shop so it might not be a good fit but they have nice hobbyhorses.
I would recommend midwesthobbyhorse THEY ARE AMAZING I have bought one of their custom ones and the quality is AMAZING! For about 190! Which is really good for a hobbyhorse!
You could always make them! I know the fabric can be expensive so you can reuse an old t-shirt or use felt from the dollar store! They're are also lots of tutorials to make on with socks!
