Final Cut Pro - why do they keep asking me!?

I've been editing with Adobe Premiere for some time. Life wouldn't be the same for me without After Effects as well. It seems to achieve everything I need.

Suddenly I've been hit with creative folks and potential clients asking whether I used Final Cut Pro. A studio is promising to throw me some work, but only on FCP. There's also a possibility that a filmmaker will want me to edit their project on FCP ONLY. I usually feel awkward because my answer will be "no, I use Premiere" and I sound like a jackass that doesn't know their stuff.

So basically, I'm feeling pressure from the industry to go this route and make a substantial purchase and learn the new OS along with FCP; though I can pick it up quickly.

Am I giving-in to **fit in** like this? If it means dinero, I suspect yes. Or should I stand strong and say I'm content with what I have (a blazing PC that handles anything along with Premiere)? If I insist on Premiere I could loose the opportunity.

Please share your thoughts.
Best-
Frank
