Peter,
The advantage of the Dioptrix is that it is made in a thin, flat, multicoated form in a mount designed to fit the TeleVue eyepieces and probably others. Should it not fit what you have, it's probably able to be removed from the mount and put in a standard filter mount.
A lens from an optical outlet would require a custom ground lens which would then require fitting to an appropriate mounting. This could prove quite expensive compared with a readymade product. As I read the advert for Dioptrix, it is up to you to make the alignment yourself. With a -0.75, this should not be a big deal, as you merely rotate the corrector to get the clearest image. Once you have determined the best orientation, you note the position of the mount relative to your head angle for repeatability, remembering that if you change your head angle as you do with a dob when you alter the altitude, you need to realign the corrector.
Sounds complicated but you'll soon get the knack.
