I personally think that they are worth it. It really depends on what you are looking for. If you are looking for a cheaper (yet still good) option, then underworks is a good option. I've personally had the tri top binder. It works really well. If you want something a little bit more comfortable (and more expensive) then lesloveboat.com is a good place to get binders at as well. I have this binder. It's nice for the summer months because it has a mesh back. It also has held up really well. You'll also have to decide if you want to have a long binder or a short binder. Both binders that I have bought have been short binders. I've heard that long binders curl up at the bottom. Short binders do this a little, but they are not as bad. If you want a binder that looks like an undershirt, then a long one is the way to go. If you want a binder that looks like a sports bra, then a short one is the way to go. Here are some other threads that might help you out too. Binders?? I need some help with buying a breast binder
I think having a chest binder is a good investment to make. Underworks 997 is the go to binder for most people, but T-Kingdom and Lesloveboat are great place to get a variety of more comfortable binders that are a bit more expensive but pretty durable. I have this one from lesloveboat and it's great.
