I'm starting basic: Spanish. I've ordered the eight lesson introductory course ($20) to see what I think before I order more. But everything I've read is pretty positive about it. Not only are there the obvious reasons for speaking Spanish for someone in the Southern US, but I have an opportunity to travel to Columbia in the future, and would like to be prepared (possibly also Mexico). If this goes well I plan on getting the Pimsleur Hindi course, It's a "compact" course, which basically means they only teach you how to operate on a basic level (get a taxi, etc), but I figure it would at least get me started. There are a couple of sites I found--Cheap Pimsleur
and Used Pimsleur
--that ought to make acquisition a bit cheaper. They even have a buy back program. I'm disappointed there's not a Telugu Pimsleur, but I suppose 75 million speakers isn't enough for 'em.
