Newbie with a SV45TE

[Visions]

Hello All!

As a newly minted convert from the digital wasteland, I am soon to take delivery of a lovingly taken care of, preowned Ebony SV 45TE.

The outfit I purchased is nearly complete except for a few things, which I was hoping you all could assist me with through time-tested experience & insight.

I would like to get a bellows hood (to fit a 90 Caltar and 150 & 250 Fuji lens), a meter for landscapes (primarily what I want to do) a changing bag for film loading, and a roll film back holder.

I read somewhere in the forum that Mamyia Bellows Lens Hood G-3 could be easily modified with Lee? hardware. Not sure what a good price is for one of these? The changing bag should be an easy find, just don't want to spend $250 for one and afraid a used one may leak. And know nothing about which roll film back is the best used or even what to look for?

Also, one other stupid question. How do you deliver exposed film to the processor?

Thank you all in advance for any and all assistance.
All the best.
