Just thought I would give some links to a source based on personal experience. I’ve ordered multiple dongles from AliExpress with GREAT results. I paid extra for DHL shipping and my dongles arrived from China to the West Coast of Canada in just 3 days!
Here are links for: 1 Dongle, 2 Dongles, 6 Dongles from Newsky being sold as model TV28T (Note: slight circuit difference from original TV28T received, but works)
Note to NEW AliExpress members, I believe you should get an additional $5 at checkout. I noticed when placing my first purchase there was a coupon available just before payment. Not sure if there was a minimum order (I spent $65 the first time for 2 dongles + DHL shipping).

Over on Michele’s GNSS blog He has supplied some interesting information on her testing with A Newsky TV28T and GPS signals. It yet again reinforces the idea of E4000 being the current “best” tuner controlled by a RTL2832U.

“For once, the group of innovators is European.
“These guys of osmocom are smart and -what’s even better- their work with the open source team. RTL-SDR is, I believe, one of the freshest finds in the Software Defined Radio domain. The Fun Cube Dongle, developed in UK, is already a very clever tool. But finding the super-tuner Elonics E4000 (note, again a UK Company) in 25$ USB DVB-T dongles and being able to grab data in a 3MHz bandwidth between 64MHz and 1.7GHz… that is really cool.” — michelebavaro
