It really comes down to what you want to do with it, versus the money you want to pay.
For me, the modded ToUcam was good value. I can do planetary stuff, and I can have a dabble at some DSO stuff. Ultimately its the DSO stuff that I'd like to be able to do, but until I can get set up on a pier/observatory I realise I'm probably never going to be serious about DSOs. But for me, there's heaps to learn doing planetary stuff, and quite a bit more to learn dabbling at DSO type stuff even if not seriously, that makes it worthwhile for me to spend the extra $200 or so. I've got more serious expenditure to make before I launch into a good DSO camera, but I'm still learning valuable lessons in the meantime.
So while a modded ToUcam doesn't compare with an SBIG or dSLR for DSOs, I still think it's good value as an entry level camera for planetary and to learn some valuable lessons before you fork out the big bucks for that good camera! But if you aren't interested in DSO's, or you want to get seriously into DSO's straight up... by all means question the LE mod.
