Papa - Polk's isn't exactly a "no-name" company. Many years ago they sold the radio division of Aristocraft (long standing brand name) and it became known as Hitec. Also, they have recruited two engineers formerly from Hitec to design the Tracker II. I agree that they are relatively unheard of though. However, untill I had heard of the Tracker II, I was faced with the same choices you have now.

The Tracker II can do everything the Eclipse can and then some, for around the same price. I especially like the fact I can change the frequency of the receiver without having to remove it from the plane, and I don't have to buy crystals for it. The only other synthesized receivers are extremely expensive (Futaba & Multiplex), and you still have to remove the Futaba from the plane to change the channel (multiplex can be changed without removal). My other favorite features include a built in scanner which tells me which channels have interference, and a 99 model memory.
