I think it's a bit pricey for a guitar in that bad shape, especially with a neck break. I know they say a well-repaired neck break can be stronger than the original neck, but it's enough to put me off.
The problem with working out the values of Japanese guitars is that they usually have a number of models at different price points, which look very similar but the details are different - finish, hardware, quality of timber. When it's 15 or 20 years old it's very hard to figure out if you're looking at a mid-price model or a top-of-the-range one, and there's not a great deal of reference info out there to help.
I have two Tokais, an SG-75 and an SG-155. They look and feel very similar, but one was nearly twice the price of the other. To most people, they're just "Japanese Tokai SGs" - the model numbers don't mean much, and they're not written on the guitars so in a few years they'll be forgotten. I could probably make my money back on the 75, but I bet I'd lose loads on the 155.
