Hmmmm.... Your desired "FGRV in excellent condition" and "Reasonably Priced" might be mutually exclusive terms.
What you are looking for is considered by many to be the "Cream of the Crop" in FGRV's and, if you hadn't noticed, August is the absolute price peak for FGRV's in excellent condition. (We just sold our 1994. 13' Lil' Bigfoot
for close to $10k.)
Waiting until the season is over usually results in units being available at better pricing, albeit in fewer qualtities, but your geographical location and travel distance limits cuts into your market for these hard to find rigs as well.
Give us a slight idea of your budget and you might get a few nibbles and/or further advice.
BTW: As it is always a topic of discussion, what will you be towing with?
