Just picked up the Bachrus "The Saddle" Series 40z 4 saddle roller kit and the add-on 2 saddle roller kit and I am very pleased with the performance of Z wheels on the roller sets. Bachrus made the 40z sets with special rollers just for Z, although you can adjust the width for larger scales. I got both the 4 roller AND the 2 roller set for under $90. The Hershey Pa. dealer on the Bachrus website offered the best price and FREE Shipping! Highly recommended.
Somegai, I always wonder why get them. Is there a specific thing it does that I cant do in the track.
