How is the 69242 different from the 69240 model?
634048
One model, the 69242 I believe, is for full frame pistols while the 69240 is for compact handguns.

I believe all of the models share the same parts. the best way to know for sure is to compare the one your trying to replace visually with the one you are looking at. Voltage and hardware in general will be the same(for this model) its the os or memory that change. Sorry I could not be more helpful.

The 6733 has 3 modes and the 6962 has 5 modes. That's the difference. Both offer 31,000 brush strokes per minute. As for me, I use only 1 or 2 of the modes at best, usually only 1. Either of these models would be a great product it's up to you on the price.

I believe it's just an older model number. I haven't found anything with any difference between the two of them.

There are many versions of this filter. 691035 is a standard filter 695666 is a longer version that has a longer life. They will both work just fine for your application.

970 (I had to look) I have the original that's 1000. It's been fabulous though --I wasn't sure which one was even the new one until I looked for you -- they are interchangeable. I bought a knock off brand once and it was terrible. It had maybe 1/4 of the life. This one, as I said I couldn't even tell the difference.

I only own the 2540, but just scanning the specs, it seems as if the 2542 is faster. I can't see any other notable difference: both offer wireless connectivity and the ability to do basic printing jobs as well as scanning and copying. They use the same inks, and the printing & scanning resolution seems similar. You may want to ask HP what the differences between them are (vs whether they are basically the same device). The paper feed on the 2542 may be different? But I can't tell without having one here, and suspect that many others out there own either one or the other but not both, and so may have a tough time addressing this question.

Both seem to be same. Here is the link from HP website. I searched for 7525 and I was redirected to 7520. http://h10025.www1.hp.com/ewfrf/wc/product?product=5286643&lc;=en&cc;=us&dlc;=en

I am not sure how accurate this will be because it is based on product descriptions I've read while printer hunting. It appears as though the only difference is the 7525 may have an ethernet port the 7520 does not, making the 7520 is Wi-Fi only.

I don't remember which model my old ones were, but the 9120B used the same wiring as my old ones. The 9120B did not use the same base or mounting bracket as my old ones, but those are easy enough to replace.

I don't know if there is a diference between models. I have it since 2012 and works great. Sorry!!

Sorry to say, I'm not sure of any difference. Both seem to be identical. I just know that I love mine and I'm sure you would too. Good luck!

A big difference for me was that the 8620 has duplex scanning. The 8610 does NOT have duplex scanning

After comparing this model vs the newer model(both are 2006 models) these seem to be the only differences: Main diff between 6187 & 6188 models is the 6188 also has: - picture in picture, firewire, surround sound processor for the internel speakers, RS232C control and I "think" the 6187 does not have cablecard(?). You can download the specs from Samsung's site and compare.

751. As far as I know the technical specs are the same and the difference is the color. 751 is darker (almost black)

I believe the only difference is the size of the filter. The x6672 is 16x25x5 and the x6675 is 20x25x5. They are both Merv 16...
