Hi John
Have a look at these guys,
Scopetronix, although I have read posts on sci.astro.amateur that they are either out of, or went out of, or are struggling with the business. Several warnings were issued about ordering from them, but things may have improved? Maybe send an exploratory e-mail to see what response you get?
Navigate to the digi scoping section and maybe try the Wizard too.
Cheers
Dennis
