I think you will find a c&c set-up much better. You can interact with the guinea pigs more and can make it bigger by adding more grids if you need to. 4 grids by 2 is an ideal size for two piggies, but 5 by 2 woukd give them more room to run around and stretch their legs! Don't forget that if you have other pets like cats and dogs you will need to cover it securely to keep the piggies safe. Then add on other costs like bedding, hidey houses, toys, water bottles, bowls, hay and pellets. The members picture gallery on the forum might give you some ideas.
