Yamaha GT-2000 from Japan or local TD-125?

Like Elliot suggests, a 120V to 100V step down transformer is no problem. You just need one that can handle the wattage of the GT2000 motor, which is likely to be less than 25W. eBay for $50-ish. I owned a TD125 for several years. The GT2000 is simply better.

elliottbnewcombjr and lewm, 

Thanks for the insight.  It would be nice to have a YOP-1 clone, but I think they are hard to come by.  In lieu of that, I was looking for step down transformer advice.  Nice to know its a cheap and generic solution.

I'm in the middle of negotiating for an "Excellent" GT-2000.  I should be able to get it at $1400.  I'm a bit nervous dropping that kind of cash for a transaction like this.  If I bite the bullet, fingers crossed that it arrives well packed and representative of the pics.  And if something goes wrong that reimbursement is not a nightmare (buyer pays return shipping, but I am likely covered by eBay protection.)

Just an update - I've negotiated for a GT-2000 for 1400 in "excellent" condition.  The pics seem to support this.  

I mentioned that I would like to take the evening to read over the details before payment.  I'm crossing my fingers that things go well from here.  

The YOP1 is an option, not a necessity.  They are usually easy to find on Japan Yahoo, if you really want one.

Thanks for the tip.  I usually just see one or 2 on eBay for $1000 or so.  I know they are not a necessity but I've heard they are pretty great to have.
