Don't let what he said bother you... he may have just been trying to warn you about how addicting this hobby can be. If you don't have much experience with crt's then you will want to do as much reading and listening to the other guys here as you can for a while. I got my first crt less than a year ago, and it has been a very steep learning curve for me. I'm finishing up my third one now, and it is very addicting.
Having fun is one thing, but effectively telling him to piss off because he doesn't already know is just being a dick.
Bemoan the CRT community dying up on the one side, and scare off the new blood on the other.
Maybe WE know he didn't mean it (though it's hard to tell) but a guy who's just showed up here sure doesn't. He asked for advice and got told to go digital. "Prepare to buy ten of these in the next year if you learn. You are doomed!" would be razzing. That wasn't.
Oh, and if you ask me, "having fun with the newbie" is a really, really stupid way to live your life. If I wanted to be among people who think that being new to something means being treated particularly badly rather than particularly well, I'd go back to high school and join the swim team.
