You're welcome, Rachel! Consider getting the Troy Lite system, for which Cathe provides a link on her home page in the Buyer's Guide; I think the Troy Lite system is still marketed through Fitness First (don't know the website address).
The Troy Lite system has a really nice, slim and short (4-foot) 5-lb bar, and various rubberized weight plates in weight loads of 2.5 lbs, 5 lbs, 7.5 lbs and 10 lbs each. The bar can hold up to 80 lbs of weight plates. Troy Lite also markets a neck pad which I find very helpful for barbell squat/lunge work (trust me, barbell squats/lunges are awesome!).
Hope this helps -
