if u want a cheap and easily replaceable one go for fiskars or some other walmart brand. they arent super durable but they have lifetime warranty and are very cheap. if you want something more durable you can try ontario knife company or condor machetes they are strong durable and also have good warranty, but more expensive. me personally i bought a pack of 5 "colombiam military surplus" (picrel not mine) machetes for very cheap 30-40 dollars if i remember. they came dull but otherwise were great and were all shaped differently for different uses ex a thick wide one for chopping, a long thin one for grasses, a hawkbill i usually use for grubbing. no matter what you buy you will need to also buy a file and maybe even a low grit stone for sharpening and maintaining.
