If you are looking for cheaper body hammers and dollies then look at Daggertools.com They have some very nice hammers and dollies, far better then any cast iron crap from Horror Fright.
You want Pro grade hammers and dollies, then look at Martin.
these are my favorite dollies. The two on the right are from Dagger, you WILL NOT find anyone that makes those styles unless you buy some super high end German tools $$$$$. They are old Herbrand patterns. The one on the left is an egg dolly from Martin.

I personally wouldn't remove the fenders for repair unless you build a stand like this. There is nothing worse then working on a panel and have it flop all over the place. You want the panel to be secured.
