Mark, there is a website with every single flight school in the US, state-by-state.
When I was trying to find a school for the same reason as you there I went through every single one and made a list. Here are my old findings:
$73 C152 Wisconsin fdlskyport.com
$75 C152 Oregon
Salem Air Center Flight Training
$79 C152 Wisconsin flymilwaukee.com
$83 C152 Wisconsin lakeshore Aviation ---- free flight for every 10 hours
$84 C152 Wisconsin springcityaviation.com --- $100 credit for every $1000
$85 C152 Wisconsin wisconsinaviation.com
$85 C152 West Virginia flyaphelion.com ----- cool website
$69 C152 new Jersey flymafc.com --- club, yes avialability. but some weird stuff on website.
$89 C172 New Jersey flymafc.com --- 2 x C172 both look in great shape
$95 C172 Wisconsin cwa-fbo.com
$98 C172 Wisconsin flysunsetaviationllc.com
$89 C152 Washington, Renton rainierflightservice.com
$81 C152 Oregon gorgewindsinc.com
Some of those never replied to my emails so I just moved on. Eventually settled with Skyeagle Aviation Academy. It used to be called something different.
Have fun with the search.
P.S. By the way, Bartolini Air in Poland (very good school by all the reviews that I have read) offers a C150 at 85 euros/ hour I think.
