Saying that about the Sony lenses has put me off going for a Sony A230/330. Although i'll not upgrade in the near future when I do I don't want to be left with loads of uncompatable lenses.
In the same situation as the OP.
This really comes down to how far you think you'll go with the camera, if you think you're going to end up a genuine enthusiast, semi pro or even pro then you'll want to start with an established platform like Nikon, Canon, Olympus etc Sony are still very next to the game and as a result the range of lens (sony and third party) isn't as great as Nikon or Canon. So my advice would be go for a well established platform like Nikon or Canon as the glass will be your main investment.
If you're just after a camera that's going to take good shots and probably only end up owning 1-3 lens then you could probably get away with Sony as odds are you're not going to be putting that much money into glass.
