Wanted-Sparse Matrix Test Problems

I am writing a package to solve sparse linear systems and would like to 
obtain some practical real world sparse matrices with which to test my
program.  If sparse test problems are not available I would kindly
accept real problems involving full matrices.  I require both the
test matrices and their right hand sides. That is, in the solution of

					Ax = b,

I need both A and b.  

A description of the problem modelled would also be appreciated.

The order of the matrix is not too important but anything in the range
of 100 to 1000 would be most welcomed.

If replying please specify how the matrix is stored and retrieved.
