Can someone share their experience (good/bad) in using FS-1 with GL-2?

Also, any recommendation on where to buy FS-1 to ensure I get the latest software (2.33)?

Did you see my FS-1 article? It's located at http://www.dvinfo.net/articles/camaccs/firestore.php. It'll work just fine with the GL1. Purchase it from our sponsors EVS, Zotz or B&H (click the Sponsors link in my signature). Hope this helps,
