I have some RIPE available. I believe they are 2 x /21's off top of head. Come with LIR.
These would be for purchase (i.e. change of ownership) not lease. Although I have that stuff as well. Both month to month ARIN as well as term commitment stuff. Prices and terms will vary. RDNS delegation a non-issue.
Let me know what you're paying per ip, and we can go from there.
