I checked a little bit around and I found three brand new reviews:
Sony Alpha 850 DSLR Review at digitalphotographyschool.
Field Test Review: Sony Alpha A550 at Ferdzdecena (via noisycamera)
Sony DSC-TX7 Review at eCameraTalk
P.S:: Amazon has a good deal on the “old” Sony Alpha A230 with 18-55mm Lens ($407)
