Getting a mod chip soon

[Memfis]

Im getting a mod chip soon and i need it to play all types of PS2 backups of my originals. And i was looking to get the apple pro installed for 60 or i wasnt sure if i should get the $100 matrix infinity installed. Id rather only spend 60 bc the ps2 already has disc read errors which i plan to fix and is kind of old but i was wondering where it is said the Apple pro cannot play multi region dvds, does that mean it cant play dvds i have backed up where i have disabled the region and made them workable in all regions? And is there anything bad i should know about the apple?
