opin'd thus:

I'm looking to purchase a Framing Nailer for a few jobs around the
house like: building a shed, a fence, dog house and would like some
clarification. I have seen 34, 28 and 21 degree nailers an was
wondering if there are any great advantage of getting one over the
others or is it just a matter of personal preference? I dont think
I'll be nailing in any tight spaces. Is there any cost of supplies
benefit in getting one degree over another?

I was needing a nailer for similar uses, and to accommodate all the
nailing jobs around the place except for finishing and brad nailing, I
got a Senco palm nailer like this one:

It's not as fast as a specialized framing or roofing nailer 'cause you
need to feed each nail by hand, but it will drive any nail from 5d to
16d (and larger with different heads) and it's inexpensive (a big plus
for a cheap ******* like me ;^) I've used mine for framing the walls
and making roof trusses for my shed and I was quite pleased with the
tool . . . .
