External Inktank For Canon Printer Ink Cartridge

[real]

Hi everyone.

I have canon pixma mp140. The ink cartridges are PG-40 or PG-830 for black print ,and CL-41 or CL-831 for color print.

I am considering to buy external inktanks for the cartridges. I hear it costs for both black and color cartridges about 2000bath.

Anyone uses external inktanks for PG-40,PG-830 CL-41 or CL-,831?

Any feedbacks and advice are welcome

Thanks for your attention.
