I checked at my local Honda dealer and they want.............$320 for the workshop manual.
Does anyone know where I can get one at a reasonable price, such as a Haynes etc.

 

Click the Manuals link in my signature.

 

If you want a physical copy, you can get Haynes at the auto parts store for $10-15.

If you want an official physical copy of the Honda manual (1400 pages or so), I know a guy on Honda-tech selling some for $50 shipped. I bought one for my exact car (1993 del Sol), it's one of the best purchases i've ever made.

Great guy too, quick shipping and good to deal with. I can vouch for him.
