This is the Asia Pacific fund I've got, through a dealing company called Best Invest:-

Only got about £5K in it, but as you can see it's beaten any deposit account or cash ISA hands down! Running costs of the fund are actually zero, the investment company (Aberdeen) pay commision to Best Invest.
Next year I plan to diversify a bit. I'll leave that £5K in Asia and have overborrowed on my next mortgage deal by £10K which I'll split between a UK Smaller Companies Fund and probably a South America or USA Fund. The over borrowing is at a fixed 2.75%, so the investments don't have to perform anything like as well as they have been doing for me to still turn a significant profit.
The key to this sort of investing is time. Don't invest money you're going to need to get your hands on in the near or middle term. Any Fund can drop a significant chunk of its value almost overnight, but if you hold your nerve and can sit it out for a year or two then they almost always recover strongly and show a decent profit in the end.
