WTB/rent: Bouldering Pad

Hi everyone,
My girlfriend and I are heading over to California from the UK on 29th April to do a spot of bouldering and are looking to buy a second hand pad to save on plane fees. Looking to spend up to $50 and would be happy to pick up in San Francisco, Yosemite, Lake Tahoe or anywhere in between. Alternatively if anyone based in San Francisco would be interested in lending/renting their pad out from 29th/30th April to 9th May then let me know, it would be much appreciated.  
Thanks

I'd had a look at rental places but they seemed so expensive it looked like buying a pad or trying to get a loan off someone was a better option.
Thanks for your offer, I might take you up on it if we can't find anything more on route. 

Pm sent ( I think) 

some nice person needs to help out Joe.  Otherwise he gets my shitty stomped out mad rock pad and my huge Metolius tri-fold pad that probably won't fit in his rental car. :)
