broggyr: Go to US Hobby Supply. I think Michael has exactly what you want. Serial on one end and USB on the other right???? when I placed my last order the other night I KNEW I should have gotten one, cause i went to Radio shack, Circuit city, Best Buy and Wal Mart and could not find one. And if you do find one at those places you may pay 20-40 bucks (I kid you not on that price). I think his are $9.95...Heck, I'm going there to order Me one RIGHT NOW, Chuck
