While Sparkfun now operates both an MC-383V and an MC-384F, the machines are quite similar and the 383V is no longer manufactured. Therefore, I have listed specs for the 384. Below the specifications info are detailed a few of the differences between the two machines.

Manncorp MC-300 Smart Feeders Key Features
New, Slim-Profile Hardware Design for Maximum Feeder Mounting and Utilization
Built-In Memory Module Links Individual Tape Feeders to Specific Component Data (value, lot code, date code, quantity, package type, index increment, etc.)
Data Values Written to Memory Modules are Retained When Feeders are Removed from Machine or Until Overwritten
Connection Through Feeder Port and Base Links Smart Feeders to Known Location on Pick and Place Machine for Optimized Setups or Quick Changeover
Automatic, Vision-Assisted Closed-Loop Adjustment of Smart Tape Feeder Pickup Position to Compensate for Loose Packaging Tolerance
Ultra-Smooth, Electronic Tape Indexing and Adjustable Peel-Back Tensioner
Optional 2 mm Minimum Indexing for Small 0201 and 0402 Devices
Optional Bar Code Reader for Component Data Entry and Verification Prior to Assembly
First of all, there aren't many differences. The 383 is a fine machine that continues to serve us reliably over 14 hours a day.
The 384 does feature improvements to the bearings in the worm drive, allowing for a couple speed settings faster than that of which the 383 is capable.
The cameras on the 384 are a bit improved.
That's really about all we've found…although it did come with a nicer, widescreen monitor.
At the time of this writing, there was a refurbished MC-383L2OV on Manncorp's site for $24,995! Be sure to check their used equipment page
