	From a purely network operations perspective: YES, every IP 
	address should have matching forward & reverse DNS.  That's been 
	beyond best practices and into the "everybody does it unless 
	they're really stupid" realm for well over a decade.  

	Reverse DNS has only become /more/ important as spam-blocking 
	efforts noticed the strong correlation between networks too lazy
	to maintain reverse DNS, and networks too lazy or evil to care 
	if they were hosting spammers.

	As for the finances...that's up to you, but I've never before 
	heard of a provider who charged extra for it.
