In my experience with both companies, I can whole heartedly suggest going with Hybrid-Racing products. They seem to stand behind their work and products with very good quality and exceptional customer service.
Too bad I can't say the same for HASPORT. In fact, I can say just the opposite.
The few dollars you may save going with HASPORT may not be worth the trouble and delay in your project that they may bring you. I know they may make great mount kits, but with the axles I ordered, there was a lot to be desired.
Here's an example of someone else's disappointment as well:
