I saw this, too. It's a good deal. I've bought a few things from Hello Music, and they're OK. They're kind of like a clearinghouse of sorts. The one thing that would give me a slight pause in regards to buying a Variax from them is that they aren't an authorized Line 6 dealer. They aren't an authorized dealer for any manufacturer, actually. That's why they can get away with advertising thing for below MAP. So what that means is that this invalidates the warranty for anything they sell. Now, supposedly, they will honor any manufacturer's warranty for anything they sell. I suppose that means if you need service, you'd have to send the product back to them, and they would get it repaired in some way. I just don't know if I'd be too excited about that prospect when it comes to something like the JTV. I'd be much more comfortable dealing with a place like Sweetwater for a little more money.
That's just my opinion. I'm not meaning to be a party-pooper...
