I've never been a fan of Pro-Form equipment. I think it's sub-standard, and really you rarely even get what you pay for. Most of their equipment is made for housewives who will only use it once a year. It just doesn't stand up to regular use. I've never used the specific equipment you linked form them, my opinion is based on the company as a whole.
Weider equipment is ok, but you're right about their price point. I would expect price to follow quality. If you are really concerned about quality, look for a decent sporting goods store instead of Sears. Sears tends to sell only those manufacturers that can meet their specific volume and pricing restrictions, and they let the quality slide as a result. Again, just a generalization, but one that is based on my personal history.
I would suggest you just pick up a decent 300lb weight set and a decent- no frills bench that is sturdy and well made. I also suggest getting a squat rack, if you can find room for it in your house. Once you have all the equipment picked out- add up the price and divide by the price-per-month of your local gym. That way you'll know how many months you go could go to the gym for the same cost. When I did this I came up with over two years... It was a no-brainer at that point and I still go to my gym.
