Personally none of the above, they all look like cheap bolt together toys (not build for serious training) with dodgy attachments. I would never consider any of those.
If I was starting over I would get a good power rack, Olympic bar and plates and a good bench.
All you need to work your body to the max.
I would not go past one of these love them and have considered selling my power rack for one of these:
MMPR Power Rack
Weights:
140KG Olympic Barbell set (Rubber)
Bench:
Adjustable Flat Incline Bench (FIBEV)
I would not go past the above, it would be my ultimate number one home gym set up, you could shop around on ebay or the like for better deals.
They also do package deals
