As far as cost, if you dont have core calipers this swap isnt much cheaper than some of the kits available.

I paid 115 for the brackets, most likely from the say place Robbins got his brackets in Branson.

The core charge on the calipers is around 75 a caliper plus the price of new calipers, around 60 a side. Rotors arent too bad, around 25 or so a side.

I havent used the brackets yet, because I didnt like the fact the brackets pulled the axles that much farther out of the housing. But, I can see with green bearings and by machining for the snap ring that issue should be taken care of.
