All receivers work do the same thing. How they do it and the quality of the components they do it with will vary.
Just about all receivers from major manufacturers will do an excellent job. Most of the cost differences can be traced to number of channels, size of receiver and paying for the name.
Both the Hobbico and Tower receivers are made by Futaba and are identical to the 127DF model. This one has been the std receiver for many years and comes with lots of radio systems.
Alternatively, the Hitec receivers are also a good choice in the same price range.
If you want a PCM receiver, prices start at U$100 and go up from there.
Maybe a good idea to put one of those in your flagship heli.
