imho, if you die-die have to choose from the list of 4 camera, then go with the A330, for the built-in stabilization feature & also to make use of your Sigma 28-200. However, if you are not limited to those in your list, then go for Pentax Kx
Beside this: freebies and other stuffs HN/Courts might include (e.g. additional flimsy tripod and other things) you can safely skip and get the real things once you know more. Get only what you need and what you know. As a start: camera and everything in the box, camera bag, 2nd battery, memory card, cleaning kit. If you get offered any UV filters as 'protectors' then ask for Hoya as minimum, skip all these funky freebie brands like SteinZeiser, Vitacon and whatnot.
Minolta. Konica Minolta. Sony
frankly speaking, the 4 DSLRs u selected are the most basic/entry level of their respective brands. They all will still give u good image quality, but dont expect their high ISO performance to be as good as the upper entry/semi pro DSLRs. Between the 4 of them, there will be some differences in high ISO, but the difference wont be much. Its so small that their difference shouldnt influence ur purchase decision.
If high ISO performance is really ur concern, you will need to get a more advanced models.
The Sony A500/550, Canon 500/550D, Pentax k-x and Nikon D90 are a BIG step up in terms of ISO performance over the A230/1000D/D3000.
Between those above, if im you, i would go for either the k-x or the A500. K-x due to the very attractive price, and A500 because u already have a Sony mount lens. The 28-200 is a good walkabout lens, and it'll save u some money cos u wont need to buy a telephoto lens.
cant say much about the D5000. Look up the other threads on the D5000 performance. But i can tell you the Pentax k-x at iso1600 works like a gem. I'm sure there are people here that can back me up on this. Anyway, lookup the b&s section, there seems to be a couple of K-x people letting go.
If you can somehow be unbound from your constraints of the 4 choices you listed, then the Kx is a better deal with the features, newer sensor and high ISO performance at a very low price of $790 with 18-55mm kit lens.
Here are sample shots of the high ISO performance.

Okay thank guys for giving me some recommendation on getting a DSLR. Well after much consideration, I feel that it will be better for me to get a decent model during end of year, and will definitely we waiting for the IT fair to get one! Since my aunt is willing to get one for me after my national exam, now I will be reading up on more reviews of different DSLR and of cos view the photo gallery to learn from the pros. Thats all
