Stroller advice

Just found an excellent condition bugaboo frog stroller for $125 on Craigslist. I know they're sold for $600 plus and I'm excited it's a great deal. Can anyone tell me if its a good stroller though from experience? I don't mind paying more for a cheaper brand new one either. Compared to other strollers should I register for a nice one or go for the fancy bugaboo? Thank you 😊
