Thanks, Tim for all the info and advice. Great stuff.
A friend has told me that Aldi has pants for like $50 and he reckons they're ok. I will go have a look at them and wear them over my work pants and on weekend rides.
I'm hoping (probably pushing my luck) that there isn't too much rain around for a while. And By starting with the leather jacket it will suffice till I can save up some more money and get some wet weather gear and boots.
I see your at Blacktown, not far from me at all, we'll have to catch up for a ride soon!
