Best mats for home/apartment?

Any suggestions as to the best mats for an apartment? I'm looking for something fairly cheap that I can practice moves on. If anyone is selling, I'd be interested as well - thanks!

get the cheap 2x2 ones from Sam's Club. they're about 2" thick and are puzzle mats w/borders. i think i scored 2 packs (8 2x2 mats each) for about $15. not good for takedowns, but definitely suffice for matwork. bjj on a budget.

they might be called fatigue mats as well.
