Excellent Product
I have been using the Sony mini DV cassettes for the last 3 years and I always rely on sony products for good quality videos..

Sony DVC-60 PR/5 - Blue
Great product!
Converted all video taken to DVD then reused tape over and over.
The Sony brand has worked better than the TDK or Panasonic product used previously.
No drop outs or annoying distortions.
Did have to buy and routinely use the Sony head cleaning tape for the Sony miniDV Camcorder.
Pricing from Amazon for all items were great!

Cheapest I could find and sony
They are the cheapest I've found and work good. Nice quality as far as I can tell.

Solid tapes for SD footage, can't beat the price
These tapes are my standard when shooting with my 2 Panasonic PV-GS300's they are rock solid tapes, always record well and playback fine even 2 years after they were recorded. They are a great value. I keep about 20 to 30 around my shop at all times for my shoots. If you are shooting SD video and need cheap, solid tapes, these are the ones you need!

Recommended by a reliable source
When I first started videotaping weddings, I needed a tape that I could count on, so I asked my supplier- B&H out of New York. They're probably the biggest supplier in the country. They recommended these tapes, and added most people in that industry use them and love em. So I started using them, and haven't had any regrets! They're reasonably priced, and seem to deliver the quality that I need! But Amazon definitely gave me a much better price than B&H did.
