Do head gasket "repair" liquids work at all?

I think I have a head gasket problem (related 1
) in my 1998 Subaru Outback. The only symptom is an overheating engine that hasn't been fixed by a new thermostat and 'checked' radiator.
I don't really want to spend $thousands on replacing head gaskets if it can be avoided. Do the fixes in a bottle work at all? I don't particularly want to link them here if they are a scam, but the brands I have found are Thermagasket, Steel Seal and K&W Permanent Metallic Block Seal.
This wiki article
at Answers.com says maybe, but is obviously vulnerable to bias.
A medium term fix would be a win for me.
I would rather hear about real world experience, rather than an apprentice mechanic saying they would never risk it.
