I have the very same rack +/- a couple of locating holes, mine is a Powerful 4x4 rack, i paid a bit more as it was part of a deal i had done.
Good price i'd say, as for quality, mine hasnt let me down, i did a fair bit off looking around before i bought mine, and i'd say it stacks up very well compared to the ARB types out there, in fact, if you can believe it, the powerful guys say that the rack is made in the same factory, (prob china) as the ARB ones !!!!!!!.
In any event, ur price is good, and the rack well time will tell i suppose, i wouldnt think u would have any dramas, the only thing is... that it is a very heavy beast... if ur going to remove it and then place it back on when u wont to go away etc, perhaps u should consider an alloy job, for me i will be doin this very thing for my next veh.
Also check the height of ur garage before u buy if u intend on having ur veh in the garage overnight etc, i had to have my rack reduced in height for it to fit in the garage, and it was a bit of a stuff around.
