Re-using old cylinders is seldom worthwhile. Get new ones. Remember that your cylinders may well be 60 years old, and to me, the likelihood that they will go, again, for 1,000 hours is very slim indeed.
Gibson chrome cylinders are a good idea to me for a privately owned airplane that flies the typical 60 or so hours per year. Most cylinders in this kind of use fail early from rust, and chrome eliminates that cause. We have these on my Champ and they are now about 700 hours old, and in very good condition still. If you truly do fly 150 hours per year, almost unheard of for this kind of airplane in private use, then brand new steel cylinders can be a good choice. But again, that's more flying than about 90% of the private owners do.

I considered it cheap for a metro NY / NJ maintenance shop at a major airport like KCDW where I am based. I'm sure it would be much less at a smaller shop away from metro airports.
