What makes me nervous about supplying a number is the limited funds thing. If it is money that can easily be dumped into a meat grinder without worry then whatever you feel like. However if you need that money for ANYTHING else DO NOT PLACE IT INTO THE STOCK MARKET.
QASP, or any other stock comes with heavy risk of loss or total loss.
Stocks are always a risky venture, at worst you could lose it altogether. Gold and Silver have NEVER been worth nothing. You may not make a killing or even a profit but it will always have some intrinsic value.
If you feel the absolute need to invest free and un-needed resources, buy a few 10 ounce bars of pure silver from your local supplier...
ON THE OTHER HAND...IF you have funds that can be risked in the stock market, you may very well consider QASP shares. Many of us here on this board have a warm fuzzy feeling about where the price is headed up the road a bit.
If you don't like a reading a particular user, you have the option to "IGNORE" them.
