In reply to Denni:
> The 18-70 on fleabay is bthe same sort of price as the 18-55 standard one so do you reckon that is a better lens?
Yes, it's generally reckoned to be a better lens, and of course it has more zoom range. Of course Dek's 18-105 has even more range, which you could consider if you don't have any other lenses.
The 16-85 is a very good lens, but is more expensive.
Or you could consider the "does everything" 18-200.
Basically, you need to decide what range you want.
(Rule of thumb, the greater the zoom range the bigger and heavier and more costly the lens, and the (slightly) worse the optical performance, since it involves more compromises.)
