I love the site, I find it's often more accurate than most sites due to the inflation of prices on sites like Star City Games and sites like TCG Player can yield distortion in their prices if someone tries selling it for an absurd amount be it higher or lower than its initial value. I found that MTG Goldfish is one of the most accurate even though it has the same problem with TCG Player from time to time and I really like the articles members of the site post up there. I'd also go ahead and check out MTG Stocks as their prices also seem to be on par.
I make all my decks using Puca Trade. I've only been successfully scammed once, possibly attempted one to two other times but a great deal of the time my Puca Trade experience has been pretty positive. One thing I do recommend is for anyone new that you insure packages over 5,000 points (equivalent to $50) because there's a loophole that can get you scammed otherwise. Also make sure you let the people you're sending to know the condition of the card before you send so everything flows nice and smoothly.
I've used the site a few times before for when I wasn't able to trade cards within a time constraint. The only thing I have to say is that there's usually a lack of buyers which makes sellers have to lower the price to considerably MSRP so that current buyers of the site will actually make transactions.
