Amazon is selling the PC 7424 for $129.99 (free shipping) but there's a 20% discount promotion going on.

Read the promotions: "The merchant will apply any benefit after your order has been processed."

 

I don't have one but seriously been thinking about getting one.

 

Why dont you go with the Ultimate Detailing Machine (UDM) instead?

 

Because this is the first time I've heard of a UDM. And because, after the 20% discount for the 7424, it would be just a little over $100.

 

i ended up going with the UDM. i think it was around 150 but it has a stronger motor.

do i need to buy a separate counterweight? my package didn't come with one but i was wondering if it's really necessary

 

Good decision. The UDM is ready to go, counterweight is pre installed, plus you have a quality backing plate and pad to start with. The bag is an added bonus as well. If you have an old PC, you can get $50.00 in credit for it. Let me know if you need additional info.....
