Good strategy building software

["Bob Pitatzidis" <bobz2335@xxxxxxxx>]

I used Tradestation a little several years ago.  I want to start again and 
buid an strategy system.  Be able to do Backtesting.
Should I stick to Tradestation?  What other software offers what I need?

For example, I was just looking at  Welth-Lab.

Thanks
Bob
