If you haven't found one, Burlington has a full competition/reversible practice mat for sale at the end of the season. Mainly black with red circle. Numerous practice circles.

It is an older resilite mat split into 4 pieces (2-10 foot pieces, 1-8 foot piece, 1-4 foot piece.) It does say "Burlington" and "Wrestling" down the edges of the competition side. It could also come with a vertical hand crank storage piece if that's something you're interested in. It's in fair condition - just upgrading! Would be more than willing to negotiate a fair price.
