This is a highly opinionated response so take it with a grain of
salt.  Being a man, I'll use any excuse to buy a new tool.  Now I've
got several tools from Harbor Freight and they serve me very well and
at a great cost.  BUT, if I'm going to be cutting a hole in my pride
and joy, I'm going to sell my left #@% to pay for the best hole saw I
can find.  I'll always find a use for it or other blades if I find a
great one that allows blade changes and if I need to help someone else
out, I'm prepared.  Especially after comments like, "A hole saw will
work but is tricky to control in that space.  Done it.  Extra damaged
knuckles job.   That in itselft says to me, "go big"  Now that doesn't
mean spend the most, but good tools usually cost more.  Good luck and
safe drilling as bits tend to grab and stop when going through sheet
metal.  The bigger the bit, the bigger the grab.  When that bit grabs,
it stops right NOW.  The drill will turn in your hand so use the
slowest big drill you can find with an extension hand.  Leave plenty
of cord available as it will wrap around your arms.  My buddies dad
had a bit grab after breaking through sheet metal.  The bit stopped,
the drill didn't, it wrapped the cord around both arms and he couldn't
let go of the trigger fast enough and broke both wrists right then and
there.  Crazy old guy drove himself to the hospital.  Don't ask, I
didn't.
  This is one case I disagree with, "Use a cheapie hole saw set from
harbor freight or similar. "

A hole saw will work but is tricky to control in that space.  Done it.
Extra damaged knuckles job.  Coming out the bottom I suspect a propex
furnace.  Use a cheapie hole saw set from harbor freight or similar.  A
couple buck throw away.

Planned insanity is best.
Remember that sanity is optional.
