If you buy from Leetmod, buy the Acekard 2i for $16.99 + $1.99 shipping. Select the 1.3, there's no need to spend the extra $1 on the 1.4FW.
If you buy from 0ShippingZone, you can buy the Acekard 2.1 for $13.50 including shipping, however they are in HongKong so shipping times will be longer.
If it were me i'd go for the cheaper option, but it depends on how quickly you want it.
