I am a titan fitness guy. Pretty much my whole gym is equipped with their stuff. I've been really happy with the quality and their customer service. I know they apparently had a really bad reputation early on for their packaging and shipping, but I've had no issues.
The only item I did not like was an adjustable bench that I bought from them. I honestly had a lot of difficulty assembling it, and I may have done something wrong, but I think it was poor build quality. I kept it for quite a while, but then wanted to selling it and just replacing it with a flat bench from Titan. I've been really happy with it and found that I don't really miss having an adjustable bench.
Personally, I would recommend keeping it simple and starting with a quality power rack, bench, barbell, and good set of plates.
