Tar-Cat
We have picked up a lot of our bits and pieces - including aero bars- on a local auction site called TradeMe - its been brilliant
Have you considered going online and hunting a localsite like this for you?
Or ask your local bike club about stuff their members have for sale... we have picked up nice wheels, a trainer and my partner's TT bike this way
Or local shops may sell stuff on behalf...
Second hand does not mean cheap and nasty - it can mean cheap and excellent

Examples---

--- my $NZ1200 Scorpio road bike bought for $NZ600 because hubby had bought for his wife and she rode it three times and didn't like it (online auction)

--- $NZ300 cycling trainer stand bought for $NZ50 because the guy from the local club was off overseas (local club newsletter)

We bought my as-new aero-bars for $NZ25, they don't have bar-end shifters on them, just the "naked" bars, but they are in good nick and ideal for getting used to the position. Good luck with finding some real soon
