I use an 1/8" to male XLR cable, and then adapt the XLR's to 1/4". Actually it's a TRS 1/4", but that doesn't really make a difference. It's unbalanced, and mono either way.
Less adapters and solder points would be ideal though.
Oh but wait.... I just remembered I have an 1/8" to double mono 1/4". Used to use it going from a Samson Mixpad to a minidisc. Hosa makes em. Got it at my local music store. Try Guitar Center if they're near ya.
Or get some quality that will last from someone here on the board (best bet if you don't need it right away).
