A mei tai is great. I got a babyhawk aswell and now a girasol mysol and they are amazing. The thing you want to be careful of is making sure they are safe and stitched together properly. It could be someone is selling theirs cheap cause they no longer need it, but it could also be a badly put together carrier that may be unsafe. Are you on facebook? Maybe join the babywearing buy sell swap group. There's often cheap carriers of all kinds that come up for sale there or someone may be able to direct you to a WAHM type business that makes them.
