That Edwards model appears to be the E-LS-90LT, but the price is surprisingly low from what I can see. Normally Katana's prices are higher than the normal Japanese retail prices, but in this case it's less. It could be a different model, but from the description it looks to be the right one.
Anyway, as far as these guitars go I personally wouldn't worry one bit about ordering it w/o playing it as Edwards' quality is great. I bought my E-LP-105LTS/RE from Ishibashi on a whim and it's fantastic. It turned out to be a LOT better than I ever imagined & hopefully I'll be able to pick up another Edwards soon. The next one is def going to be an E-JR-95LT/RE which is a TV Yellow relic'd LP Junior or maybe a E-TE-98M/RE which is sorta like a relic'd Keith Richards "Macawber" Tele (both lacquer finished).
You could always e-mail a retailer like Ishibashi, Big Boss, or Ikebe with the model info and see what the best price is they can give you on it. Many times they'll give you a better deal on it than what's listed so it's worth a shot.
If you'd still rather try before you buy then it's worth checking into the LP Special Faded models, but be sure to try out a bunch as their quality seems to vary quite a bit. If you find a good one then it'll probably be quite good and they can be found used so deals are out there. If you don't mind buying used then keep an eye out for one of the early 90's Specials as they made a limited run of them and from what I remember the quality was very good. I think they made them in a run of 500'ish? Maybe it was more like 3000...meh, it's been a while so I don't recall offhand. Either way they were nice and can be had at good prices sometimes too.
With that said I think your best bet for a Made in USA LP Special-like guitar has to be the Hamer Special. Their workmanship is amazing and their guitars just ooze quality. A Special can be had for next to nothing (I've seen mint ones going in the $400-$900 range with most on the lower -mid side) and they're an amazing deal. Also if you can spare the dough check out their Korina Artist & 25th Ann. models. Both are the same Special shape, but with an arched top and some (maybe all) are semi-hollow with P-90s. They can usually be had for really good prices too, but a bit more than the Specials. Oh, and they also made some Korina Jr.'s and Specials too, but they command some decent bucks.
Anyway, hope this helped some and didn't confuse you any.
