Query: Kettler Ergo Racer Review

I bought the Kettler Ergo a couple of years ago to do indoor training when the weather gets bad. Quickly -Pros: *Very solid feeling. The eddy current wheel is very smooth, quiet, and provides plenty of resistance when you dial up the watts. Good adjustment possible on both seat and handle bars.Cons: *For the money, you'd expect software included. I paid over $1,500 and that rankled me that it is not included. *Outdated serial port interface on unit. Few new computers have these. I just recently purchased a Serial-USB converter cable. Finally I can see if I can get the 3rd party software to see if it will work.Overall: Very satisfied. I prefer a solid, quiet trainer that works to a noisy, cruddy one with good software.
