I got my first DSLR in 2007, I'd separated from my wife, she'd "banned" me from bying one for a year or so, I had some money to burn and a mate that worked in Jessops..... it was enevitable that I was going to own a DSLR
He was very knowledgable and I had a play with some lower end Nikons/Canons, the Canon 400D felt best to me and the spec was fairly similar to the Nikon..... what probably swung it was he could get more discount on the Canon too
Anyway..... I left with a 400, Sigma 18-200mm and various other bits and pieces all for about £700 (RRP nearer £950

)
For the first couple of years I was groping around in the dark really...... Not venturing out of full auto mode much. Soon found out my lens wasn't long enough to cover rugby/cricket so I bought a Sigma 170-500 which saw me good for another year or so then the relatively low pixel count (10MP) of the 400D, max ISO1600 and only 3.something fps started to hold me back as I got more serious about taking shots at rugby matches.
By this time I was venturing into full manual mode as well as Tv/Av with the latter being my primary weapon of choice.
I've waffled on a bit here but my point is if you haven't ever owned a DSLR it's going to be nigh on impossible to know what *you* want/need. There's no point in spending thousands on top of the range gear only to find you could have got the same results spending a fraction on the money.
So perhaps look at entry level to start with, most entry level DSLRs have 10MP+ now. Kit lenses aren't bad but you can be a little restricted on range. Might be worth considering a "super zoom" lens i.e. 18-200+ although the compromise at the lower end of the market is IQ, when you're starting out the versatility would probably outweigh that.
Once you've been shooting for a while you'll soon work out what you can/can't do or what you'd like to do and upgrade as required.
I still have my 400D/18-200mm as back up so it's by no means a waste of money.
