GREEN HOUSE's GH-CRHC44 USB memory card reader has six card slots that handle 44 types of card - all the common variants of SD/SDHC, Compact Flash, MemoryStick, etc. What's the point of 44, when the ELECOM MR-A47H already works with 47? Well, the GREEN HOUSE is a lot cheaper: JPY1380 vs JPY4410. On sale from mid-October.
