I'd suggest that you buy more plates for your DBs. You'll need those one way or the other. I hope you'll go ahead and buy the Olympic bar too. But if you can't afford it all right now, then get the plates first. When you get ready to buy a bar, go ahead and get the big Olympic bar. Don't bother with the smaller bars. You'll outgrow them very shortly too and wish you'd gone ahead and bought the real deal.
