[IIgs] Buying a Hard Drive for my old IIgs

[rwgomez@hotTHIS-IS-ANTI-SPAM-TEXTmail.com (R.W.G.)]

I am in the process of bringing my old Apple IIgs out of retirement
and am interested in getting a hard drive. Back in the day I never had
a hard drive, so I haven't the foggiest notion of what took look for
as far as brand names, or what to look for when shopping around.

Is there a specific brand/type of drive that anyone could recommend?
Are they still being produced? What is the approximate cost (in $) of
one new or used?

T.I.A.
