Scrap mboards, he has a history of not delivering or delivering wrong items and not replacing them.
As mentioned above, out of the Hub options which are available now, the Meepo hubs might be your most convenient option.
@jeffwuneo is going to produce a second batch of his Hubmotors which are adaptable on any truck. The first batch ships right now to members of this forum. If you are a bit patient you can wait for the outcome and get on the second batch. I am considering buying them myself.
Direct Drives in general are more expensive because they are mechanically more complex compared to hubs. The cheaper Direct drives are coming only with Double Kingpin Trucks, which are a sort of specialty truck, people hate them or love them. In general they are not as stable as usual RKP trucks. I have set mine up with stiff bushings and got used to them, but would still prefer RKP trucks.
Don’t rush yourself into buying stuff too early, I did spend a lot money because I started replacing parts after one week due to underwhelming performance.
