Heat wave clone semen price$

I am buying a semen tank from my uncle and he has some heat wave clone semen left. I am not sure what clones yet but I was just wondering what the goin rate is for the clone semen. I checked lautners website and see only about 5 clones listed out of the 15 or so there is. Most are at $30/unit except Heat Wave1 that says ask.  Is there a big difference in which clone the semen would be from and is $30 a good price for any of the clones.

Heat wave 1 usually sells for around $100/straw. Other clones are $30/straw. Don't know why anyone would pay more than $30/straw for a clone but some do.
