The cheapest / best value in cable and satellite TV service? I am looking around at different cable TV and satellite options, and it seems overly complicated and ultimately very expensive. What are the best deals available at the current time, and how can I keep the costs low but the service still reasonable?
Z scale is the fastest growing scale in model railroading today. Some Z scale manufacturers offer briefcase layouts; entire track layouts with landscape, buildings, and a power supply all in a briefcase. These are high-end executive toys that sell for around $1,000.
Most motors used in model trains today are brushed DC permanent magnet motors. These operate at maximum speeds around 10,000 rpm (some can operate at higher speeds) using gear trains to reduce the speed at which the wheels turn, and thus can be rather noisy.
