Argentina, Dec09-Jan10, bike for rent?
 

Hello, I'm planning to do a trip in Argentina, from Buenos Aires to Bariloche or San Martin for about 10 days. The dates can vary but I'm thinking starting just after Christmas till 10 or 15 January 2010. As I live in Madrid it doesn't make sense to ship my bike, but I've been checking out the different renting options and they are a little expensive, even though I've seen very positive comments about some of the outfits there.

I would like to know if somebody has a trail bike for rent in a more "home-made" way. I'm confortable with any 600 and + bike (Transalp, F650GS, V-Strom) or even a tourist one as I'm planning to go 90% on tarmac.
Could pick up the bike in Buenos Aires or in the south.
Thanks in advance.
