The short answer is that there is no short answer! Much depends on the size of negative you scan, your purpose for scanning, how much time you have, and your resolution/quality requirements...oh, yeah...and budget. If you are scanning 35mm, have tons of slides to archive, have little time, and need better than 2400 dpi...$$$$$$
If you are scanning MF or larger with the same requirements...
To balance the above...almost any decent film scanner will deliver better results than what you get from the minilab...regardless of the size of file they deliver (garbage bigger = bigger garbage). Entry point is around $200 USD.

mucho dinero used) and Epson V700 (for 120 and 4x5)...also has a Microtek flatbed that cannot be given away...)
