Good and affordable alternative to PCI tile products

Does anyone know good and affordable alternatives to the following PCI tile products?

- PCI Gisogrund 10L (requirement 40 liters)
- PCI Lastogum Grey 8kg
- PCI Lastogum White 4kg
- PCI Pecitape 10x10
- PCI Pecitape 90° I
- PCI Pecitape 90° A
- PCI Pecitape Object 120mm
- PCI Nanolight Flex Mortar 15kg (requirement approx. 1500kg)
- PCI Nanofug Premium Cement Grey 5kg
- PCI Silcofug E Cement Grey 310ml

The alternative should be of similar quality but cheaper.

Can someone recommend good brands to me?

Here in the north they like Lugato. But it's not low cost either.
