I found these patched madras shorts for $10 each. Both are 100% cotton, made in India, and seem pretty authentic to the touch. Not sure how to test if they'll bleed, they might have bled enough already. The shorts on the left are Rugby by Ralph Lauren, which Fred E. Castleberry over at Unabashedly Prep has often mentioned. On the right is a pair from a label called Company 81. Their website leaves much to be desired, but the shorts seem pretty solid.
If you just can't get enough madras, Christian over at Ivy Style has a nice post on how madras gets made here.
