it's not often you see the upper end (ls 150 and up) on the second hand market.they're not common though so it's not surprising either.above ls 150 you start paying for fancy tops etc so on these models the 'value' is less apparent (to the cheapskate).
I don't think it's necessarily people being cheapskates, more that most people aren't aware of the differences between the different Tokai models. The model numbers are confusing - and hard to remember - and (visually, at least) it's hard to tell much difference between one MIJ Tokai and another. So I reckon one of the reasons people don't sell high-end Tokais is that they know they'll never get their money back!
I have an SG-155 (or SG-175 now, unless it's changed again). There's nothing on the guitar to say the model name (except a tag in the case, which most people wouldn't have). In a photo it
looks exactly like an SG-75, and frankly it
plays almost exactly like an SG-75. OK, it's got a one-piece body and a nitro finish, but the average punter looking for bargains on eBay doesn't know that. I couldn't sell it without making a HUGE loss!
