Hi Kat,
For a wald 139 I use a 5 rail Pass and Stow, built by Matt Feeney in Oakland, CA. I've had mine for 17yrs and counting. It supports a 139 completely for and aft, with just a little overhang on the sides. It will carry quite a load. It is $295 USD, so likely a little over budget, but it's well worth it IMO.
Mine is one of the first he made. (Here it is with a 139 on top.) If you look for a 139 wald basket on Blue Lug's website, they show it mounted to a Pass and Stow as well (better picture). They currently have integrated dynamo light wire routing and mount (on the right side). Cross bars on legs can hold panniers.
Check 'em out:
Happy shopping!
-Peter
