I got an off the cuff quote saying it would be about $400 (assuming no surprises) for the conversion from local Auto A/C shop. A number of years ago I got a quote from the Acura stealership of $1,700 for conversion of the Integra (fortunately it's still working fine on the freon).
There's no point to getting the Spider working as it never really gets hot enough to be a problem. We relish the few days/weeks we get over 80F.
