Of course the SHM-CD version is going to be expensive. First off, it's an import from Japan, which makes it more expensive in the first place. And then it includes an SHM-CD, which means they'll charge even more for that. As for them, I found that if you have a cheaper CD player, you might hear a bit of improvement over a regular CD. But if you have a decent or excellent CD player, they're not worth the extra cost.
I did find a site that has the deluxe set for $110 US and the 2 LP Vinyl set for $28. I don't think that's too bad a price for either edition.
