Flex! I bought my Flex after i did my first detailing for my friend's car with a PC!
The pc shakes too much, my finger hurted after playing with the PC for 9 hours....

But then, The flex is a totally different story, muich more stable and more power, allow me to polish faster!
to me, the Flex really worths what it is priced!

This should help you on your decision

--------------------------------------------------------------------------------
Pro's
--------------------------------------------------------------------------------



· More power than a Porter Cable 7424 or Ultimate Detailing Machine ·
The Flex offers 9600opm & since it's a direct drive, it also offers up to 480rpm. The PC and UDM only offer up to 6000opm and no direct drive.



· Better cutting ability ·
Because of the higher OPM and the addition of RPM it will cut much faster then a PC/UDM



· Faster breaking down of a finishing polishing ·
The addition of force rotation aids in the breaking down of polishes faster. The Porter Cable can finish to a high gloss, it just takes longer.



· Still Safer than a rotary ·
Even though it is force driven, it's still a R/O so there is less risk of damaging your paint (though still possible).



· 13ft cord ·
Comes in very handy when working around the car.



· Variable speed trigger ·
This is one of my favorite parts of the Flex. This allows you to start slow and spread the polish without having to change speeds. I also like to slow down the speed a bit when finishing so this is beneficial when the polish is broken down too.



· Will not bog down when pressure is applied ·
Again the forced rotation allows you to apply pressure without the worry of bogging down the machine.


--------------------------------------------------------------------------------
Con's
--------------------------------------------------------------------------------



· Cost ·
For the price of the Flex alone you could get a nice PC starter kit that would include the PC, backing plate and a variety of different pads.



· Only One size backing plate available (as of now) ·
Since the gear for the direct drive is on the backing plate, it's not interchangeable with common backing plates. Flex at this time only offers a 6" backing plate for the Flex, so you are forced to use 6" or larger pads. Edge system is working on an adapter for their system though.



· Not as easy as a PC for a novice user ·
Since it's force driven it requires more control then a PC/UDM. It can grab, skip and jump a bit just like a rotary.



· Still does not have the speed or cutting ability of a rotary (definite step up from a PC though) ·
but the risk factor is definitely lower.

You guys must have something else going on. IMO, Nebster's post looked like a helpful one to me, although you didn't seem to take it as such.

FWIW, very good decision on the flex. I will be upgrading from a pc to a flex myself.
