What is the best motor & howto (www.ftatalk.com)

http://www.ftatalk.com/showthread.php?t=135856

I too intend to put a motorized dish up, come spring.
But I am getting conflicting arguments as to which is best, I don't want the cheapest, but on the other hand I don't want to lay out something I don't need to.
Some here are suggesting to go with the STAB make over the SG version.
Here is a quote from a large local professional installers web site.
Anybody with experience in either have any comments?
Thanks
Max

Why the SG2100 is better than the Italian made Stab units:

1. Wind Resistance: According to the structure of SG2100 it is also good for 140Km/h with 90cm Dish.
2. Corrosion Resistance: The treated screws we used can pass the Salt-Spray test for 300 Hours.
3. Temperature: Sorry we didn't mentioned it on our spec. We have made many tests and the SG2100 is good for -40degrees C to +80 degrees C. We will add it onto our spec.
4. Sensor: One sensor is already good enough. Only the one who can't write good software need 2 sensors to reduce the possibility of miss counting. Besides, the count's precision of SG2100 is 0.0256 degree but not 0.15 degree as STAB mentioned.
5. Precise '0' position: As everybody knows that SG2100 has very precise 0 degree reference. We use very smart software to calibrate. No need to adjust the mechanical parts of SG2100.
6. USALS: USALS is only a software for the receiver to calculate the Azimuth angles of the motor according to the Latitude, longitude of the end user and the Satellites want to aim. We have the same tool in our website. We call it GAAPS (Global Automatic Antenna Positioning System). All the end users can use this tool via www.gaaps.com.tw . We will prepare more information for easy installation with the help of GAAPS in the near future.
7. Power Consumption: Since the output power of the Receiver is at least 350mA, 180mA consumption will not cause any problem. The reason we set the consumption higher than others is to offer low backlash at any azimuth angle of SG2100. STAB has lower consumption, however, the backlash is very large while the motor is close to 0 degree.

STAB wants to hint that higher price is equal to good quality, however, it is not true for the market. It is a responsibility of a good enterprise to offer good quality with better prices, right?
