8.25% tax this '13 fy.
-- mini-DVR $88.50 + tax 8.25% =$7.30 = $95.80 total. no shipping fees to U.S. from DX.com . This YouTube shows the unit up close. TF card looks smaller than SD card. The video calls it a microSD card and thinks the Chinese are calling it a TF card. TF-to-SD adapter $4 at DX.COM Don't use the charger - it's not safe and total junk. It'll charge off USB into the DVR itself. Wait; make sure you get the version that saves in .avi format. Chris Angelos says he has been fine with the Supercircuits DVR. DVR and VTI for second occn station for students - Richard Nugent: I would highly recommend the ebay mini DVR's with the 2.5" screen (all digital). I have had two of them, and have recorded over 750 videos (mostly double star drifts). These DVR's are the size of a credit card and 2cm thick and use SD cards. A 4 gig SD card will provide 5 hours of video. They record in AVI format directly readable by Limovie and Tangra with no conversions necessary. (File format conversions do run the risk of data loss/ changes)
Here's a sample 67-second video of a double star drifting with GPS time insertion on my you tube account:
http://www.youtube.com/watch?v=yAokhR1UR_I The file size of this 67-sec clip was 2.4 Meg. Thus a 5 minute video (typical for occultations) would generate a 11 Meg file size--highly manageable for our applications. This You Tube video was degraded in quality after I uploaded it. This here YouTube from a British sounding reviewer is pretty complete, but not for astronomy
