Judi's very nice and helpful
I get the impression that Judi gets a lot of units where her hands are tied related to how low she can go on the prices due to demands of sellers.
Before I bought my 1 Bd platinum at the Flamingo, I was talking to her about buying a 2 Bd gold there instead. I didn't know all that much at the time (even though I had been looking here to try and figure things out), and I was seriously considering buying the 5000 point from her for about the same price as I was going to pay for the 4800 point unit. I called her and talked to her about it, and she said to me, in no uncertain terms, buy the 4800 platinum plan instead of the 5000 point gold plan, as the resale value is much better and the maintenance fees are much lower.
There's no doubt in my mind that at that time, Judi could have easily snookered me into buying the package from her (perhaps by lowering her price a couple of hundred dollars). But she was very honest with me, and pushed me to buy from a private party rather than her.
I've never dealt with Seth, but all of the positive press he gets here from people who've dealt with him, along with his honest comments on the board, suggest that he's well worth doing business with. Despite never seeing Judi post here, I have to believe you can't go wrong with either of them.
