I bought a set of roof racks from Micks garage out of Ireland. I got the last set of steel aerodynamic bars made by a company called Menabo. I consider these excellent quality and were made in Italy, and included locking plates for the bolt downs, as well as very good instructions. I chose the steel ones in case I wanted to modify or drill them, which I needed to do to mount my Thule roofrack. The Thule has t-slot adaptors which would have worked well with the aluminum racks that have slots, but I may be mounting other things on the roof as well.
Here is a
link to what is offered there now.
I am unfamiliar with the G3 racks, but hear they are pretty good.
My racks were $138, plus surprisingly low shipping of $20. I think there was a coupon code for 10% off my order as well, so search it out.
All in, delivered to my door for under $200. I was very happy with Mick's garage, the speed of the order, etc.
Now I can mount my 10' playboats on the roof using foam adaptors, or have 3 or 4 bikes go on a trip. I'll post the part number if I can find my receipt.

It also allows me to tow a trailer and take my bike with me:
