Bogen Manfrotto 3063 Tripod Head w/ Pan Handle & QR Bracket
They call this a Mini Fluid Head but there's nothing mini about it. It stands at 5.75" and weighs in at 3.25 lbs but has been quite the work horse. It supports up to 11 lbs, pans 360 degrees, and tilts from -45 to +90 degrees. The reversible pan handle can be placed on either side of the head. (You'll need a metric allen wrench to assemble the two-section handle after shipping.) Nice smooth motion. This head has been used over the years on a Bogen 3046 tripod supporting an 80mm scope and also 50mm binoculars on a parallelogram mount.
$65 (REDUCED) which includes shipping in the CONUS by USPS Priority Mail w/ delivery confirmation and insurance. Payment by a non-credit card Paypal transfer preferred but will also accept a Postal money order or a Bank check.
P.S. This will fit tripod legs with a 3/8" bolt. I believe you can buy a 1/4 to 3/8" adapter if needed.
