Joe, I use a Hood Press, Charlie does not make them any more,
but Scott Crawford does. Go to the classifieds in BR Central for info.
My personal preference is the Hood design, not saying there is anything
wrong with the Harrell"s.
Overall the Hood has a tighter feel to it, less movement in the linkages, and
slightly more compact in storage. The Hood handle is quite tight to the press
body and does give some folks issues, while the Harrell has a more stand-offish
handle and is easier to grasp.
The Harrell has a nice c-clamp built onto it so mounting is very easy even on
2x4 or larger benches. Hood mounting plate (removable with hand screw) must be
clamped onto benches with standard c-clamps or using holes provided bolted to bench.
On my traveling table I have t-nuts mounted so that I can use hand screws to attach
the press (or other tools, case trimmer, powder measure stand etc.) by using several of
these holes I have some flexibility in positioning these items.
Hood presses are a little more pricey.
Maybe Robert will jump in on this one as he uses a Harrell press also.
