The first thing to keep in mind is the current availability of Personal Reel Blanks.
I have had the best luck on ebay, so below I have provided links that search specifically for these items:
This to Search Ebay for View-Master Cameras
Click This for more extensive search (may give you other stuff as well)
Click This to Search Ebay for a View-Master Cutter
General Stereo Camera Section on Ebay
Other sources are local camera shows. You might get a great deal that way.

3DStereo.com also sells top quality cameras and they all come
with a warranty.
This is typically the more expensive, but you wont get stuck with a camera that has problems.
