Best grids to use?

I like the ones from Target and Shopko. The grids from Shopko come in purple, green, pink and I think blue plus white, black and chrome.

Make sure the grids you get don't have a plastic coating. Because I know lots of pigs like to chew the bars, and the plastic coating will peel off.

I like the grids from Target because a) I live near Target b) Walmart is so crowded it makes me insane c) BB&B and LNT are way out of my way d) The prices listed online were all comparable within a few cents.

Guess that isn't a scientific reasoning is it?

I purchased a set at Fred Meyer this week: they were just aweful to put together! I looked at Target, there were more in the box, and they were cheaper! So I got a couple boxes. I got them home and the connectors looked almost identical to the ones from Fred Meyer ~ but they just snapped on ~ SOOO easy! I took the Fred Meyer ones back!
