I concur with holyroller. I've seen a definite uptick in values and sales for Spanish language domains and have brokered the sale of two in the last month (one which was a quick turn-around from a expiry).
However, I think you're stuck dealing with the challenges of any .info. They have potential, but are more dev dependent (imho) than .com/.net.
The raw domain then I would expect/would price at circa $10-20 wholesale and $30-50 for a development end user. If the domain were developed and seo'd into a stats/fan site with a forum that saw decent user traffic, I'd be willing to significantly up the ante based on traffic/membership volume.
