Thanks for the quick replys, I have had a feel of quite a few in jessops and like the feel and setup of the Sony more.
I understand the bit about the lenses and have got money for them ontop of the camera itself, are there differences in the quality of the lenses made for the nikon than the Sony lenses for example, or is it more of a case if you get what you pay for?

I use Sony, so I'll tell you about what I'm familiar with. Taking the third party manufacturers first (Tamron, Sigma etc), they make most of their lenses available in all of the major mounts so there's no difference between them apart from the mount on the back of the lens. So (for example) a Sigma 10-20 in Nikon mount should be no better or worse than one in alpha (Sony/Minolta) mount. When a 3rd party lens is fitted to a Sony body, if they have in lens stabilisation this will not work as the body stabilisation will take effect. Note that with Sonys the body stabilisation means that even 25 year old Minolta AF lenses will be stabilised.
With the body manufacturers "own brand" lenses, again they all make some very good lenses. What you get with Canon and Nikon is more choice, especially beyond 300mm focal length, as apart from the 500mm mirror Sony don't make any longer primes (500/4 is coming), so the only options are 3rd party or s/h Minolta. At the wide end all the manufacturers have it covered. I use an old Minolta 17-35/3.5 which is lovely, nowadays Sony do a 16-35/2.8 Zeiss autofocus lens - puddleduck on here has one and his pictures with it are super (those are both full frame lenses), but there are cheaper options from 3rd parties and
second hand as well which are still good.
Basically you can get really great lenses in all the main mounts, but for the top ones expect to pay

. There is no shortage of economical and
second hand options either (some people forget that Minolta AF lenses made since 1985 fit Sonys, as Sony bought the DSLR business from Minolta, and wrongly assume that the s/h choice is poor :nono: )
