I have a double drive which came with my Sinclair Spectrum disk 
interface - the MGT (Miles Gordon Technology) +D.  However, in my 
experience, they rarely come along for sale on Ebay and suchlike. I also 
once saw a 3.5" and 5.25" double drive unit on Ebay but missed out on it 
by a few pence!

I would imagine that all the parts in a double drive are as replaceable 
as a standard single-height drive.  The transformer parts are pretty 
much off-the-shelf components and the drives in mine are just normal 
single drives, jumpered, but in a double height case.
