>>3004022SQ-As are hard to find here. Been trying to simply find an 80mm to replace mine with a dented filter ring. I've only seen 2 SQ-A setups in my 18 months of living here and visiting camera stores relatively frequently. They are quite common on yahoo auctions though and a good looking setup goes for about 25,000-30,000yen.
In terms of weight its not light...but I don't hesitate to throw it in my bag when I go hiking or out to photogenic places. Probably no heavier than a Canon body with L glass.
