Professional Racing HID's?

Okay I've reached a point where my 9" china made HID's are falling below my needs. I've been eyeballing all kinda lights and haven't found anything worth pulling the trigger on.

I've found the Hella Rallye 4000 euro beam & I like it, but it's only 35 watt and its possible to convert it to 55watt on your own.

I use my rig for work and they offered to buy upgrades off my "wish list"
But it's very hard to explain random purchases through PayPal to tw folks to have someone convert for me, much easier to find one legitimate vendor that'll just sell me a package deal to the accountant.

Anyways, my question is
Where do I buy already converted 55w hella's?
I assume "Pro" competitors who run baja, etc dont run consumer grade lights. Where do they get em?
And
What's the highest wattage HID available?
