Good info, thanks. Of course here in the UK we're going to get screwed.. my preferred vendor - who is generally cheapest on everything he stocks - shows it at £60 which is $90.
Damn annoying how we seem to pay the same figure in £ as it costs in $, despite the 1.5:1 exchange rate! Especially when a lot of this stuff is coming from China anyway.
Oh well, it's still going to be everything you said for £60/$90 anyway!
The best price I have found in Canada is 99.99. I can't remember if that got you free shipping or if it was $10 on top for that. Realistically for a genuine Yihi chip with or without the temp control and dual batteries to boot...its good value even if it can be had for $60 in the US
