I know all about "HG" from talking with Dutch and Jean at G-Fest, including a story about a particularly wonderful trip he and a couple others took to his house(s).
I don't know if I'm going to try to get anymore older toys from him; his prices the the majority of the newer stuff from the past six years isn't too bad, I got a couple Godzilla 2000's for $45 each and a Megaguirus set mint on card for $90, both of which are a little higher than on eBay but I think Scott Horton had both of these prices this year at G-Fest. I know Clawmark has much higher on both of them right now.
I won't tell you what I spent on the MIJ Perf. Tag '91 Godzilla and '91 Mecha King Ghidorah; I got pictures and they're both in outstanding condition from most of the toys I've seen of these two models so I'm not really upset about what I paid.
I can say I haven't put myself into the position of even being able to be conned with a bootleg because I'm so specific when I ask about toys, but if what I've heard is true than I think I'm going to limit dealing with him as much as I can on the newer toys at all, and try to avoid completely any of the older toys. The hint he gave in the latest G-Fan toy review that he (tries to) sell his 1992 Bandai Biollante for $600?!

That damn thing better ship in a solid gold box, or something.
His eBay auctions are quite ridiculous. I remember reading one for the first time and just thinking "what the hell is this?" Oh well.
Yeah, Destroyer, I'd go with Mike Johnson if you can. He's got good prices and good toys, the one toy I did buy from him got to my house so quick that I wondered if he mailed it out before he even got my money order, no kidding.
