The 2000 bubble wasn't that bad, unless you were poorly diversified.
The FTSE seems quite high atm, I'm waiting for a fall to invest some more.
I don't think you can go too far wrong with a diversified portfolio of bonds, shares and corporate property. There are 'absolute return' funds as well, which are quite interesting if you are risk adverse.
Hargreaves Lansdown market a selection of funds that they recommend: www.h-l.co.uk/funds/Mark-Dampiers-Wealth-150
Be aware that they do add things hastily sometimes, so would look for a record of performance over time.
Take for instance:
www.h-l.co.uk/funds/fund_performance/sedol/3303126
add in the 'UT UK Equity Income' sector, and you will see there is a good record for that fund against its benchmark.
www.h-l.co.uk/funds/security_details/sedol/0479019 is a Financial fund that I bought prior to the credit crunch, and through good management it has actually gone UP 22% in that time.
