There's mostly Sankisk on that list. I found this other list, which seems to have more options. Who knows when was the last time Tascam renewed that list
And I did buy the Lexars from B&H, they recommended it themselves.
We know then they last revised the list: 2015-10-06. http://tascam.com/product/dr-70d/downloads/
And we know that they (more precisely TEAC Japan) tested these cards themselves with this recorder.
In contrast, the list from the memory dealer you linked means absolutely nothing. It is simply a list of currently available SDHC cards which they sell. "Compatible with" means it's the correct card type and capacity; that's all. They haven't tested any of those cards with the 70D.
B&H may very well be recommending a card that works fine. I hope it works out for you.
Also, those prices are high too! They have a 32gb SanDisk Extreme Pro[on Tascams Approved 70d list] listed for almost $37! You can get a 64gb SanDisk Extreme Pro SD card CHEAPER than that directly from SanDisk on Amazon
Here's a link to the SanDisk Extreme Pro SD Cards[the link below is for the 64gb version, which I have successfully ran on my 70d's for MANY hours and highly recommend]!
64gb SanDisk Extreme Pro SD Cardhttps://www.amazon.com/dp/B007NDL54C/ref=twister_B009RVUYAY?_encoding=UTF8&psc=1
And just for reference, the 32gb card that is only $23, compared to the $37 listed on your link https://www.amazon.com/dp/B007NDL56A/ref=twister_B009RVUYAY?_encoding=UTF8&psc=1
I would def stick with the SanDisk Extreme/Extreme Pro[the model #SDSDXPA-016/32/64/128G SD cards on Amazon/etc] or something on Tascam's "Approved" card list that I posted again for you below, and buy directly from SanDisk on Amazon to avoid getting fake cards! As always, YMMV
Anyway, here's the link for the Tascam 70D Approved card list again, that Voltronic posted above!http://tascam.com/content/downloads/products/867/dr-70d_tested_media_list_20151006.pdf
I have PNY Elite SD Cards[32gb + 64gb] that I also got on Amazon, but early in 2015, directly from PNY, and have had flawless success with those as well, plus they're a little cheaper than the SanDisk Extreme Pro's. But since the 70d is such a steal price-wise, I figured that I would get the more expensive SanDisk Extreme Pro 64gb SD card[since its the best/fastest sd card on Tascams "approved" list for the 70d, which Voltronic has posted above] after needing a 2nd 64gb SD card for my new to me 2nd 70d, after buying a FAKE PNY Elite SD card from eBay a few months ago when I got my 2nd 70d! But I feel that if I went with another PNY Elite from Amazon again instead of using eBay, that my 70d's would probably work great with it. However, I didn't want to deal with yet another card that didn't work with my 70d's since the fake PNY Elite from ebay didn't work at all[kept getting "Write Timeout" errors], so I went with the SanDisk Extreme Pro because it was 100% verified to work with the 70d, since it was on Tascams Approved card list. So the extra $$ for the SanDisk Extreme Pro over the PNY Elite was well worth it to me! And the SanDisk Extreme Pro works great with BOTH of my 70d's[I tested it in both for MANY hours lol], so now I don't have to stress out while I'm recording and worry about running a non-approved SD card in my newest 70d and worrying if it would have a "Write Timeout" error or not. So the extra $$ was sooooo worth it to me
That said, the SanDisk Extreme Pro has been great and worked flawlessly so far, so I would buy another one of those in a SECOND over the cheaper PNY Elite
