Need a DSLR

I am thingking of getting a DLSR. Not for family use but for a more serious matter.

I've been trying to sell stock photos but a 'bridge' level camera just can not keep-up with the high requirement of the stock photos reseller website / portal.

But, my budget is very low. And I am really having a problem making my mind between current model. Nikon D3000, Canon EOS 1000D, Sony A350 (older model which is very cheap now!... but 14Mp maaaa.......)

I am a live view type of photographer... so chances are... I am going to go fo the A350........ but..... still thinking..... he... he... he............
