All versions of the Pi are supported, from the cheap Pi0 to the 4k-capable Pi4. Unless you wish to do 4K there's no reason to get anything more expensive than the Pi0.
Shipping within the USA is $4; outside the USA it is $15 (sorry, but that's my actual cost, international shipping is very expensive).
