From an interesting German arcade parts vendor, uncovered by Mark Shaker :
http://forum.arcadecontrols.com/index.php?topic=82203.0BRAND NEW SNK LS-30 Rotary joysticks. 
I didn't realise they were still being manufactured ?
http://www.arcadeshop.de/Joysticks-Rotary-Joystick-SNK_538.html*** Has anyone ordered them ? Are they GENUINELY Brand New, or just re-furbished / re-conditioned ? ***The website does state (if it can be trusted) :
" This item is absolute new. If you buy this product you receive full warranty by law. "I've read these sticks are "pin compatible" with the Happs mechanical rotaries, so they can be used with Ultimarc's Rotary Joystick Interface :
http://www.ultimarc.com/rotary.htmlThe price of the SNK rotaries would be approx.
55.42 Euros each, plus international shipping.
The base price of 65.95 includes 19% VAT. This is a tax which only applies to E.U. residents.
From the website :
" Our prices include German VAT of 19 %. This VAT could be substracted, if and when your delivery address is located outside of the EU. "Doing the math : 65.95 / 119 * 100 = 55.42
