I don't think there is a related product in the UK. If there is, I would love to know about it, as it would help me with my job. (Can someone else help?)
It appears to me that it would be considered more of an investment product than a life insurance product - you put in some money with the hope of getting good returns, and in the event that you die before you take the money back, it goes to a beneficiary.
I think the best route would be to think about what you will need the money for, and use that to find out what the best product would be for you.
An easy way to find an adviser is to go to
www.unbiased.co.uk, but I think you might need one who understands US and UK tax issues, as there could be tax implications when you cash out the policy.
Also, regarding your statement that term policies and policies with no cash payouts are poor value, I can assure that you companies that provide cash payouts and/or do not limit payouts to a term account for this in the cost of premiums, administrative charges and/or the amounts they pay out in the end.
