I got mine from Powerhouse. After I'd ordered I carried on googling and only then (typically!) did I find a few negative reviews wrt delivery/communications. Sure enough my kit did not turn up when it was supposed to, nor on the next 2 weeks. Feel I was fobbed off/bullshitted by them when I phoned to enquire/complain. It did eventually turn up though (3 weeks late), quality of everything was great and price was good so not too bad in all. I would probably use them again (but not if I were in a hurry!)
I got the Bodymax CF475 rack (very solid, recommend it, plus it's a bit cheaper now than when I bought it!) and the Bodymax 145kg Olympic Rubber Radial Barbell Kit. The weights are good for the money IMO, I like the way they are easy to grab because of the cutouts, and I like the rubber coating as I haven't bothered to build a platform yet or get any matting. Haven't had any problems like Craig describes, perhaps I just got lucky though. Certainly they aren't a premium product. The bar has bent very slightly but again is OK for the money. I'm going to get some more weights (probably bumper plates) and a stronger bar for deadlifting soon.
I did look around on eBay/gumtree for second hand racks, there are always a few about but they are normally beat up pretty bad, plus you've got the hassle of driving out to collect it (you will need a van!). You'll probably have to take it apart yourself before you pick it up as well (unless it is welded in which case moving it would be even more hassle).
Second hand plates are also easy to come by but seem to go for nearly new prices a lot of the time, I found PH were quite open to doing a bit of a discount when I bought all my kit at once so that's what I did in the end.
