What kind of combine harvesters to BUY for 20 acres of wheat?

What kind of combine harvesters are my option if i need it mainly to harvest about 20 acres of wheat , i prefer "reputable brand (name brand) , sack and unload , compact design" . what are my options here ? and it would be great if it could harvest something other than Wheat too.

i own 50 acres, laborwork is really costy around here (side note : i live in egypt and everything is done by hand over here.) i saw these chinese small size combine harvesters and i am wondering wether there are some "brand label" of them as i am not a fan of Chinese products :)

(i have heard about the Yanmar CA 385 but cant find any info about it)
