HPS PzC disks for sale?

[krmiller]

As I understand it the disks are not compatible with the JTS Gold updates and it appears HPS no longer has any Tiller updates on it's site.  You would have none of the updates or bug fixes available if you purchase the disks second hand. 

Also several of those titles were released after Tiller and HPS parted ways and were never available on disc.  Your best bet would be to buy the games from JTS during one of their sales and/or use the multiple game purchase discounts they offer.
