The last one in the list is $250 off!
And at 100mbps, it should be fast enough for Magic Lantern RAW video I don't know where my brain is! You need 1000x or about 150MBs for Magic Lantern RAW video. Sorry about that!
Speaking of that, I sure wish that the manufacturers would stick to one speed rating! 1000x is not the same as 100MBs. From wikipedia, the “x” rating is a multiplier.
CompactFlash IDE (ATA) emulation speed is usually specified in “x” ratings, e.g. 8x, 20x, 133x. This is the same system used for CD-ROMs and indicates the maximum transfer rate in the form of a multiplier based on the original audio CD data transfer rate, which is 150 kByte/s.
R=K * 150 kByte/s
where R = transfer rate, K = speed rating. For example, 133x rating means transfer speed of: 133 * 150 kByte/s = 19,950 kByte/s ~ 20 MB/s.
These are manufacturer speed ratings. Actual transfer speed may be higher, or lower, than shown on the card depending on several factors. The speed rating quoted is almost always the read speed, while write speed is often slower.
