You may want to try TS3se since there's more tools in it...Actually,there are tools in it,yeah.
What I mean,someone prove me wrong please,is that TSx1 free edition has a good renderer,BUT lack low-polygon modeling tools...For instance,no welding or collapsing so if you import a model in it,you will see a seam between all faces so you'll have to do everything manually...Whenever possible though.
I'd use it if it weren't for that....
Still,you'll find it useful if all you want is a Grid Snap because there is one in it if I remember correctly plus,from what you may already know,the software runs like hell in a 32-bit environment.
Or maybe will Raven come and tell us where it is if there's any?
Just remember that you're standing on a planet that's evolving
