I am a proud owner of an EX-30. (Some of my work is quite large which is why I chose the 30). I started with an entry level saw, and quickly realised that I needed something more substantial and suited for heavier use. If you are in the same situation, I would advise that you research well, and consider you're budget. Dewalt, Hegner etc also offer some very good, high-end saws - but when you're spending that kind of money...take you're time. Find what's best for you, then don't look back. For my work, it was the most logical decision I could've made and I'm delighted.
If you require any more information, just give me a shout.
Kindest Regards,
Nick.
