6x24 LED Array - Where to start?

My project is eventually going to use a 6x24 LED array. There are a couple things that I would like to get help on before I start though.

First, what is the best/cheapest way to circuit this? There seems to be so much information out there with different ways of approaching this.

I sort of want to chain together three 8x8 RGB Matrix together, but i only want to use 6 rows instead of 8.

I need a cost effective solution for doing this.

Thanks!

Can this be achieved with several MAX7221 chips? If so would someone be able to explain how to connect them?

I may just stick with single Red or Green LED matrix instead of the RGB.
