Unless you ahve money to burn I would go with a HF set of ball peins. For a guy that will use them occassionally they work great. i have had a set for close to 10 years and only have one that is failing. That was due to some ding dong missing his swing and hitting the fiberglass handle. Still useable but not worth the risk.
I also have a dead blow from them that works great too. For what you use it for it should hold up fine.
Then I have a BFH that was a hand me down, no idea of the make. The final blow (pun intended) would be the sledge. I figure if I need that on a car I have bigger problems to deal with
Just my $0.02 but you may not need a SO piece for you purposes. If I used my tools everyday or hand money burning a hole in my pocket I would get SO but I don't so I have HF or Tool Town in Canada.
