Firstly, I apologise if there's already a thread relevant enough for me to post this in, I just didn't fancy sifting through pages of topics. 
Right...I'm currently looking for an entry-level DSLR so I can start up my own portfolio and hopefully make a bit of a career out of this hobby. I've narrowed it down to three cameras, but as an amateur, I'm not completely sure what to look for, hence my being here. I'm looking to spend around £500 maximum and I'd like a twin lens kit if possible. Here's a little run-down of info I've gathered thus far on the cameras I've shortlisted. Please feel free to correct me, suggest alternatives or anything else you want to add.
Canon EOS 1000D with twin lens kit(£479.89 from Argos, but knock 10% off that due to the discount I can receive).
PROS:
Good value
Quality pictures
Live view feature
Relatively cheap to buy add-ons
CONS:
The long range zoom lens (75mm-300mm) has terrible reviews
It looks so much more basic than the 450D
Generally it looks a bit boring (I know this isn't hugely important, but you wanna be getting a nice-looking product when you spend over £400).
Sony Alpha A200 with twin lens kit (£429.99 from Argos. Again, I'd be able to get 10% off that).
PROS:
Looks lovely
Some nice features
The lenses have MUCH better reviews than the Canon do
It's surprisingly cheap
CONS:
No live view feature
It's a Sony (to me that screams "we know very little about cameras and more about televisions and stereos", although I could be very wrong)
Add-ons are a lot more expensive than Canon
Olympus E420 with twin lens kit Most places online have this priced at around £350-£400.
PROS:
It's Olympus - haven't they always made good cameras? :|
It looks nice
Apparently it's the worlds smallest/lightest DSLR
It has live view
CONS:
Expensive to buy add-ons, as with the Sony
To be honest, the price puts me off - there's something not quite right about that
LCD display looks a little more complicated and less-pretty than the above two cameras
So...am I even on the right page? Have I totally missed the point? Any suggestions would be very much appreciated - thank you.
