Hi all

i have decided to purchase a camper. 

my plans are to find a vehicle that will reliably allow me to travel to and
from several weekend bluegrass festivals each summer, no further than 600
miles away. i prefer a hookup for a sink and power, and air conditioning
would be nice. two people, a couple instruments, and light baggage will be
the maximum load.

i have three questions:

1.) how much should i expect to pay for a RELIABLE vehicle--will $3500 do
it?
2.) what should i look for in terms of reliability (models, years, features,
etc to avoid?), and 
3.) where is the best place to look for such a vehicle--CA is not out of the
question.

thanks for ANY help you can offer. i am ignorant in the ways of the VW
vanagon camper!

thanks
