200 Kit - HIDS 4 U or HIDS DIRECT?

[DanB720]

I have retro-fitted projector lights to my 200 and wish to upgrade the H1 (Dipped Beam) to HIDS. I have been reading and I need the ones with the can-bus wiring to prevent radio interferance. I however cant see the difference in the two following kits from both websites, apart from the price:

http://www.hids-direct.co.uk/h1-55w-new-smart-canbus-hid-kit-slim/

Anyone got either of these? Are there better ones out there?

Thanks

I fitted standard HID's from HIDS4U and had no issues with interference at all, I thought Canbus systems were for the bulb error warning?
