D1 & D2 share a frame and wheelbase so they should fit, but don't quote me on that.
The Onki units are universal fit, meaning you'd have to get a set of brackets separately, which would likely be pretty pricey.
I had a set of Romik boards on mine for a few years. Looked great and bolt on. Still readily available. Since price is a factor I'd say ebay/craigslist/u-pull-it are your best bets but even then you're probably looking at $200-$300.
