If you're willing to wait a bit, hobby link Japan has it for ¥1600 (about $16) and the cheapest shipping estimate is about $6. So you're looking at about $22 total. Downside is they're currently backordered and expect to ship in "4-6 weeks" and the cheap shipping is SAL that quotes an estimated delivery time of "10-30 days". So if you order today it *could* be 2 1/2 months before you see the package. But realistically I bet it is quicker. I've no idea how long it will take them to restock, but once they do, my experience with SAL shipping is that the estimates are often much longer than reality. Most of my packages have arrived in 10 days or less (often under a week) when using that shipping method. But I've never ordered from hlj.com before today myself, so who knows.
Anyway, here's a link if you need ithttp://hlj.com/product/BANN04459/Sci
