Hard to recommend anything without knowing a bit more
If you are looking to ride parks though you really want to consider a modern bike - stronger, lighter and cheaper than Old School!
Plenty of second hand bargains come up - main considerations to look out for are cromo all round, sealed bearings etc and most importantly perhaps the right size frame for you to feel comfy on it, how tall are you?
If you can get to a Rad event there will be plenty of people that will let you try a bike out for size, whereabouts are you based?
