Spread betting the FTSE seems pretty direct and simple enough.. also stop losses can be set so theres no infinite loss situations..
I do have lots of time on my hands and am interested in these info services..
http://www.arbwinner.com for example looks like an interesting system.. The min amount for each of the top 30 or 40 even at 100 Euros in each account still needs 3 - 4k in the bank prior to taking bets.. However its an interesting diversion and being able to pull in a bit each month (given that I am not busy and so its not distracting a full time job) is making me more curious..
