I just got my order from the Big Cheese Rodent Factory (BC). I have only ever ordered from The Mouse Factory (TMF) and so I was curious as BC has a good reputation and everyone says they're product is clean and healthy looking.

My comparison:
BC is far less expensive than TMF. Shipping is way less also. The people who answer the phone and take the orders were very nice and they got the product out the door the day after my order and took 2 days to get to me by bus.
Both places pack really well and use lots of dry ice which my teenage loves because he can then make.... oh well.....never mind!!!

Both places put there product on a tray and vacuum seal the trays.
TMF rats look like they've been bathed and neatly and lovingly arranged on each tray. There is never any feces or broken limbs. There is barely any smell when blow drying them after thawing. They always run on the small size.
BC rats are dirtier, though not dirty. They are kind of shlopped onto the tray. There is no evidence of feces or broken limbs, but the fur is dirty and yellowed on several rats. I can live with this if they don't stink when I blow dry them after thawing which I won't know until next Thursday evening.They look plump and large and I'm glad I ordered different sizes!

So, next week I will conclude this comparison with a smell test and the biggest test of all~ my snake's reaction to new rats!
