Barbells
You will be really happy with any of the following:
ABC BOP220 ~ $400 (Australian Barbell Company)
Texas Power Bar ~ $500-600 (neg.) (gymandfitness or underground elite)
Pendlay HD Bushing Bar ~ $550 (Muscledriver AU or gymdirect)
Rogue Ohio Bar or Rogue Castro Bar ~ $450 (Rogue Australia)
Again Faster Team bar ~ $300-330 (Again Faster)
or if on a budget you could take a look at:
Muscle Motion
220cm Olympic Black Oxide Barbell_Needle Bearing_Rated 600kg
I haven't seen any reviews yet, but it looks like a decent bar for the $$.
Power Racks
The commercial gymdirect rack is more solid than the Powertec rack or standard Muscle Motion rack. It has a large footprint so you need space/height in your gym area. It has a great monkey bar chin up bar & stable dips but no lat tower option; it uses sabre safety rails.
(This is the best choice for powerlifting)
The Powertec rack is nice, it has great dip handles, better spotter rails, a good lat tower option but poor chin up bars. It also has a compact foot print.
The Muscle Motion equivalent offers monkey grip chins, passable lat tower option and weak dip station; it uses sabre safety rails.
Any of these set ups is fine for a home gym and will handle pretty much anything you can throw at it.
