was it rear wheel or front wheel? that makes a difference, front wheels tend to be cheaper.
either way, you have two options:
1. re-build the wheel with a new rim. When rims are bent from a single catastrophic event, spokes are usually fine, so if you rebuild the wheel you can use the same spokes unless you have reason to believe the spokes are otherwise fatigued (e.g, you've broken some spokes at random recently - this is likely only with the rear wheel). you'd need to find a rim with the same ERD (effective rim diameter, basically a measurement of the depth of the rim with deeper rims having a smaller effective diameter and thus requiring shorter spokes). Easiest way is to tape your new rim to the old one, and move the spokes over one-by-one (they're already laced properly) and then bring the wheel up to tension. This depends on whether you know how to true or tension a wheel, or want to pay a shop to do it for you.
The Alex DA16 is listed on Alex' website as having an ERD of 597mm.
You can download the spokecalc spreadsheet
, which has a database of rims and their ERD. Sort in excel and look for 700c rims with an ERD of 597mm.
2. buy a new wheel. this may be cheaper and easier, and is definitely the best way to go if the bearing races on your hub are already pitted.
