When I bought my GS100K from PriceJapan they also offered me this 2 filter filter kit. It's $26 dollars and comes with two filters and can be seen here: http://prodb.matsushita.co.jp/product/info.do?pg=04&hb=VW-LF43W

What I'm wondering is if this is any good and if either is multi-coated. It appears as if one of them is, so any assistance is greatly appreciated.

I would just by a filter or 2 (or 3) locally.

There are no shops around here that sell filters w/ a 43mm thread. Ritz Camera in the mall is the closest and they advised me to order online. I was just wondering if I should go with that 2 filter kit or a B and W filter from B&H Photo.

I would just buy a B+W, Hoya, Cokin or Tiffen from B&H. A UV and a linear polarizer.

If you didn't get the filters from pricejapan when you first purchased your gs100, it will probably not be worth the price in terms of shipping, etc. People also seem to like Hoya super multicoated thins, if you can find them in the 43mm size.
