If this bike is what you want then yes it appears to be a good deal. Expense usually is the biggest turn off to most trying to break into the sport. This bike will do a lot and last a long time. Ride the heck out of it, enjoy it and have the peace you didn’t have to spend $1,000+ on a bike. I would ride it.
If you’re new to the sport and buy a used bike, try to get it into a shop to have it looked at before buying. A used bike will probably need a fork service, and might want to have someone inspect the wheel bearings.
