I am also having a dilemma on which 3d Blu-ray player to buy for my LG TV. And yeah eBay is not so dodgy though I prefer looking and buying stuff at Amazon or Best Buy. I am thinking if I am going to get Sony or LG.
The Imax 3D titles released by Image Entertainment (Ultimate Wave, Grand Canyon, Legends of Flight, etc.) typically sell for between $13-$15 on Amazon.com; 7 Wonders of the Solar System 3D also goes for $12.50 on Amazon. Definitely a good place to look for cheap 3D.
Bestbuy has about 40 3D titles $19.99 and less. If you have some old DVD's that you don't need, they will give $5 each if used to purchase a Blu-ray $9.99 and above. Edited by RolandL - 7/17/12 at 10:57am
