None whatsoever. The HMC150 doesn't require class 6, it requires class 4.
I have been sticking with all my new cards being Sandisk due to being a little paranoid about card issues.
I mostly use the Sandisk HD video cards in 8 & 16GB with great results. I bought a few Sandisk Extreme III cards on sale, but the performance is essentially the same as the HD video cards.

What I don't like about SanDisk cards is that they do not use standard speed class system. Maybe they think that their fanboys know the rates by heart. Whatever the case, if it takes more than 20 seconds to find out the speed class, then to hell with them.
Also, though I am not sure about it, it seems to me that the speed class is recorded on a card when it is manufactured. Again, I am not sure about it, but when I put Class 2 Panasonic card into the Canon HF100, it told me outright that it could not record at 17 Mbit/s rate. I did not even try recording, I only tried switching to 17 Mbit/s mode. I don't know what speed class do SanDisk cards report, but if they don't report any, then I see potential for incompatibility. If they want to single themselves out, fine with me. There are people who like Infiniti badge on their Nissan, but I will stick to cards that obey standards.

I've been buying the 16GB Transcends off Amazon lately, which just keep coming down in price, Class 6 for 38 bucks, free shipping.
I wouldn't be opposed to trying a Class4 card if the price is right, but I really don't see the appeal. What I don't want is a brand I don't trust, as reliability is absolutely paramount.

Not sure what you're referring to; I'm looking at an Extreme III and it has the "Class 6" logo right on it.

Look at the "10" in the circle or "C"; that's the standard logo for Class 10.

And here's a Class 4 card:
Touche. I am retracting my rant then
Maybe they started doing this just recently. This one is SDHC but has no class rating on it:

My old Ultra II doesn't have a class rating on it, but it's possible that came out before there *was* a class rating system. I think I got that ultra II like five or six years ago. It's possible that picture you're showing is from an older card prior to the class rating system coming out?
I have lots of 150x Transcend SD cards I use for photography but there are no class markings on them.
As I read it - a card claiming to be 150x is Class 6 - is that correct?
Can these be used too? Don't have my 150 yet - hoping to pick one up next week - and it would save some cash if I can use the cards I already have.

This is true. But the question remains.... will they still work?
Much of the shooting I do is in short bursts ( < 1 minute per scene 'before' editing), so I don't always need a high capacity (16GB/32GB) card, and having a shoot spread across multiple numbered cards is not always a bad thing.
