Mercury Props
 

Who has the best prices?

check the classifieds out in prop section. There are some decent priced props. BBlades is another good place that is fair.

I bought a set from boatpropellerwarehouse.com. Cheapest I could find at that time.

Try looking for a set for the new 400s that actually perform well and what is posting the impressive numbers with those motors...

It depends on what you are looking for. I always worked with Blades. They have a great prop swap program and are great to work with. If you're looking for a specialty speed type prop there are other manufacturers also out there. BBlades does make some of their own props but also supplies a whole slew of other brand names.

Thanks guys, what I'm looking for is a set of 32 Mercury Lab props.

For what you are looking for if it was me I would just go to BBlades as I said earlier. Their prices are competitive and I have never had a problem with them. If you find out you need a different propeller than what you had them send to you they will swap it for something else they have as long as it is not damaged. Im sure there are people on here that use some other organization but Im just conveying my personal experience. I have bought a few props thru them and have had great service everytime. They will also be able to lab it for you if needed. They have a web site at BBlades.
