do a quicky search...
But the short answer is: Yes
Long answer is the "HD" are home depot labeled models. Some claim that they are not as well built as the SP, and thats why the SP cost so much more.
Look at the adjustments; try to get the infinately adjustable, rather than the taps. The taps work fine for th emost part, just nice to have.
Also double check that the SP didnt come with another package, such as a cart, double tips, extra spools, etc etc...
There were also those who said the sp 175 was identical to the SP 130's, and that the 130's were just underrated.
In my use, the 130's feel to be more like 150's, but not quite a 175. Having never used more than a single (non lincoln) 175, its hard for me to say.
There isnt much support from HD in regards to supplies, etc but those 10% coupons every so often make it worth while...
