Mine is the 40cu ft. I'd say get the biggest bottle you are
comfortable living with.
And yes, the exchange programs work great because some times you go a
long time between refills.
I think I am on about my fifth bottle in about 10 years. With that I
restored two cars and did a few dozen small jobs.
When doing a lot of welding (car bodywork) you might have to replace
the bottle a few times. When just doing odd jobs, it might last years,
which makes renting the bottles like the shops do a bit silly.
