I prefer a C&C since it's easier to build it bigger when you want too and you can also design it however you want. You can buy grids at Kmart, Target, Walmart, Bed Bath & Beyond, etc. Then buy coroplast from Home Depot or buy a coroplast base from this website. Then you can get any pattern of fleece you want from JoAnn Fabrics or Walmart. Or you can choose Carefresh bedding, wood pellets, or Aspen or Killn' Dry Pine.
I vacuum my cage out every other day since I have fleece and full out clean once a week where I put everything in the washer with a clear detergent (no softener) than when it's done, I hang it outside on my clothing line! If I had bedding, I would scoop out the feces and pee every day or every other day and scoop everything out once a week. For both methods, use a 50/50 white vinegar and water mix to clean the coroplast!
Also, if you use fleece, make a kitchen area using a plastic box with an opening and use any of the bedding above so its easier to clean out the box (since guinea pigs will go to the bathroom where they eat) and so the hay doesn't stick to the fleece as much!
