Porter Cable model question

[RandallNeighbour]

I'm considering the purchase of a P/C random orbital sander to detail my cars...

What are the differences between the 7424 and the 7336?

I found a brand new 7336 on ebay for $125.00 + 12.00 s/h. Good deal or not?

The Skinny On Porter Cable Polishers By Coastal Tool

I think the offering by Coastal Tool is pretty good too.

most people use the 7424, well most people I know at least.
Check the autopia-carcare and autogeek.net sites and see if they
offer flexible backing plates and pads for both. Using a rigid backing
plate is a little riskier.

Thanks 98, I bought one from Coastal tool just now. They're price is better and you get both the 4 inch and the 6 inch pad and counterweight.

Now my question is whether to move up to the 6 inch. Do you P/C owners use the 4 or 6 when working on your Boxsters?

I've actually graduated to a 7 1/2 inch pad... benifits are detailed on this web page link... http://www.properautocare.com/ad712inhipa.html

Does "graduating" to the 7.5 inch pad require the counterbalance be upgraded, or will the 6 inch one that comes with my new unit work?
