How long is piece of string? Any suggestion would be a shot in the
dark. What's your experience and what do you consider "reasonably
priced"? Are you starting from scratch or do you have existing
photographic equipment? What sort of panos did you want to make,
spherical, gigapixel, partial , single row, multi-row, etc.? Each item
you mention is a separate topic in itself and depends on your personal
circumstances an requirements.
Cheers,
Daniel.
