I wonder which is better? a GF? or a second phone?
A 2nd and 3rd GF..
That's an awful lot of maintenance costs for very little return...
I'm with eddie13. Marginal maintenance costs go down quickly as the number of GFs increases.
Hence the well known proverb.
One GF is too much. Two is OK. Over three, my cup of tea!
(The proverb is made up, but it does ring true doesn't it?)
