Be careful what you wish for.
If you get bitten by the MF bug you may end up buying half a dozen different MF cameras - TLRs, Folders, Box etc.
If I new then what I know now I would have skipped the four cheap cameras and bought a good TLR or MF folder at the beginning of the never ending journey !
My favourite cheaper MF are Yashica 124G TLR and Agfa Isolette II.
My Agfa Isolette II was purchased from a very good camera restorer in the USA - Jurgen.
I got the lovely blue one on his front page - looks great and is a joy to use.
Fully manual , 6X6 , feels great in the hand, good clean lens and accurate shutter .
It is 50+ years old and if i treat it well may go another 50.

Save up, bite the bullet and buy a nice camera for a couple of hundred dollars, you will keep using for many years while the cheap one will get two rolls of film through it and then you may get fed up with its lack of quality or it breaks.
120 film is not cheap to buy or develop so using a half decent camera may help reduce the wasted shots.
Just an opinion from one who has spent too many dollars on cheap cameras but persisted with MF and love using it.
