which software is best to run stepwise linear regression

#1
Hi there

I need help to solve a problem actually i want to do stepwise linear regression and my predictors are 2279 (differenct combinations of soil and satellite indices) to estimate crop area (independent variable). After every run i will exclude those variables which will be negative on the pretext that crop area can not be in negatives, well i was using spss to run this regression but is very very slow and after three four runs it stucks....

pls help some body

Stata runs regressions instantly and is command line so if you get finger happy more power to you :D. Minitab is also a very lite program.
