Funnily enough, I can get a full set of the tuners from the US on eBay, for less than the total cost of buying one from hipshot, plus the import duties are paid. So that was an option I was seriously considering. I have a replacement neck for Sienna, as I really cant get on with the neck on there already. The new headstock is around 2mm thicker, which means the shortest string posts of the staggered set are going to foul (it's a leftie headstock so the shortest post furthest away from the nut has to handle the thickest string). Having worked out what I have in stock, I already have 3 x 21mm posts, 2 x 20mm posts, and two 19mm posts, so I need a 20mm post so I can go 21/21/21/20/20/20 rather than 21/21/20/20/19/19 as is currently. If I DO buy a complete set, I can use what i need, and then pop the others on the current neck and sell it complete, so that is an option. Thanks awfully chaps, I knew I could rely on you good people! Tally ho!
