Under $500 is a difficult call - I have owned and used a range of
alternatives. The Sigma 18-125mm isn't really much better (you would not
like the distortion as you often shoot buildings and street scenes); the
Sigma 17-70mm f2.8-4 is a possible option, the close focus is great fun,
but actually it's not that much better than the 18-70mm Sony for regular
subjects. The 18-200mm Sony/Tamron is not all that good; the 18-250mm is
far better, and in fact, we use the 18-250mm as a 'kit lens' - it was in
use alongside the 70-300mm SSM last weekend, and on many subjects when
used around f8 in the 100-150mm range it looks sharper, not less so -
very good resolution. But $500 may not be possible.
Personally, I use the CZ 16-80mm and that remains my unshiftable choice
- it is so much better than any other lens in its class, though it has
predictable and correctable CA especially at 16mm. I also have the
16-105mm Sony, it's nearly as good but has a slightly softer look.
I do not know how the Tamron 17-50mm f2.8 works (they have been unable
to supply a loan lens in Alpha mount) but I would avoid the Sigma
18-50mm f2.8 as the focus tends to be all over the place.
If you asked which one, single lens I would want to have it would be the
Sony 18-250mm. My daughter shares that view, she uses Canon
(18-55+75-300 IS) but borrowed a Sony kit for a recent road trip, with
the 18-250mm - she is now having withdrawal problems and doesn't like
the Canon kit any more, wants an 18-250mm, and of course you can't get
it with stabilisation and the Canon has to use IS lenses.

That's my edit for stock sale of the snaps she and her boyfriend took
using Sony A100 and A200 plus the 18-250 and an 11-18mm (easy to spot -
the extreme wide angle New York pix etc!). The sheer range of subjects,
scales and distances tackled by the 18-250mm is great.
We just swapped this lens (Tamron version) for a Sony version which is
better - it focuses faster and quieter, and seems slightly better
centered with less aberration at the tele end, probably 'clean' half a
stop wider open.
