Question about training costs

I'm looking into Westwind Aviation in Phoenix
http://www.flywsa.com/

But I wanted to know what everyone thinks of these prices.
Private Pilot Course
8 Weeks long
Ground School (60 hrs)
40 Hours Dual Instruction in Cessna 172R/S
10 Hours Solo 172R/S
1 Multimedia instruction kit
Preflight/Postflight Briefing (24 hrs)
2 Hours 172R/S FAA Private Checkride

$10,600.00

I've heard anywhere from $5-8000.00 for the private pilot license.
Is that just for the calculated hours, without adding in ground
school? The wet rate is $106/hr & flight instructor is $39/hr. (Damn
Oil Prices)

If I go the commercial route
Private Pilot $10,600
Instrument Rating $14,200
Multi-Engine & Single Engine Commercial Pilot Certificates $14,300
Airline Crew Orientation Program $2,800
Flight Instructor Certs (MEI, CFII & CFI) $11,800

332 Total Flight & Simulator Hours
47 Total Multi-Engine Hours

$53,700 Total

Just thought I'd check before making the investment.

Any advice would be greatly appreciated. :-)
