What's the deal with Lyle and Crazy Redd?

[Java]

I really don't know what to do whenever they come to my town in Animal Crossing.

So what should I do?

Should I even bother talking to Lyle or becoming a member of Crazy Redd's store?

Crazy Redd has some good stuff sometimes, but the painting he has can be fake, not too sure about Lyle but I think its a scam

He made me buy from him once, he wouldn't take no for answer, and he actually gave me 100 bells for tripping.

But today he made me buy from him again. We'll see what happens.
