Saunas! Infrared vs. Traditional

[mike31154]

Looking to hear from anyone who has experienced both to see whether it's worthwhile to build a traditional sauna (wood fired or electrical) or if I should just pick up one of those IR units that all the home improvement centers are peddling these days? I understand the IR ones don't actually get very hot inside, the light hitting your skin from the IR lamps is what gets the sweat going.

After a hard day on the slopes, a sauna always seems to relax my aching back.
