I'm writing this so people like you can come and read about the Gold's Gym Stride Trainer 380.First I'm a 59 year old white male that has been out of work for 2 years and living on a budget.Money is tight so going out other than looking for a job is not an option if you know what I mean. I grew up with free weights and have always used them to better myself at what ever I did. So finding my self out of work I felt I need something else to keep myself better fit.I,just like you looked around at many differant trainers that ranged from $200 dollars to $4ooo and there are many out there. So I picket a name brand I knew and used and trusted for years,Gold Gym.I picket this unit for 2 reasons,price and I liked the feed back that others left and I had to make a choice. I can honestly tell you it was a good choice!I put it all together myself,not sure how long it took I wasn't in any hurry just took my time making sure everything was there.It all went together by the numbers very smooth with no problems.Most of everything used to tighten the bolts is done with the alen wrenches that come with it. You will also need a small philips head screw driver and a 1\2 inch box or end wrench not enclosed. The trainer works on 4 D-cell batteries or a 6 volt power supply not enclosed. Do your self a favor and buy the 6 volt power supply. I am very impressed on how smooth it works and I really like the smart workout with the 6 step workout and heart meter.When you first start out take it slow and easy,listen to your body, you can stop and get off and rest a little and go right back to where you were.The 6 step workout last for 30 minutes. Well this is a new journey for me and if you buy this unit it will be a new journey for you as well. So good luck and let the good times roll. Alan in Visalia California.
