Would agree with most every thing you said, except that the last Gaboon I bought was less than $80.00 b.f. so it is still there to find. And no, there is nothing wrong with the quality of the wood.
I don't doubt that as there are always pockets of dealers who have stuff laying around and don't know the current market. When whomever you purchased that from goes to re-stock, they'll be in for a rude awakening. At $80 per BF for turning squares, we'd take every bit that they could supply and buy them a steak dinner.
It's just not realistic to expect to pay $80 per BF for turning squares these days. Sure there are always the exceptions if you are willing to wait to build a cue and you get lucky. The bottom-line: $150 (+-) for turning squares nowadays is the going market.
There is strong money buying up huge inventory of ebony right now at wholesale levels and stocking it for the long haul. It's better than the stock market and CD's. :grin:
If you think $150 per BF is a lot; wait 2 - 3 years and then let me know when it's $350 per BF.
