I have that same tubing notcher, but haven't tried it yet. Hopefully I have better luck than you!
A few years back I picked up their Horizontal/Vertical metal cutting bandsaw:

The biggest problem with it is that the blades HF sells are crap. 100% crap. I picked up replacement blades at HD which made a HUGE difference. They cut much faster and lasted longer. There are companies on-line who sell even better quality blades. The saw will cut steel, but it takes a while. The result, however, is a smooth and accurate cut - much more accurate than you'll ever get with a chop saw. I bought mine before starting to build the 2nd Hummer I made, which was made from various sizes of aluminum tube. For aluminum, it was fantastic. Cuts were quick and accurate. There are a few ways the bandsaw could be upgraded to make it faster and better, but if you plan on only building a vehicle the size of the Seven, I wouldn't bother. Based on the price and quality for that price, overall grade:
A- Grade for the HF bandsaw blades:
F
Another good product (for the price) is the 4-1/2" angle grinder:

I currently have 4 of them. One for a cut-off wheel, one with a grinding disk, and two with different size flap-disks for sanding welds. I've burned through 4 or 5 of these in the past, but considering they only cost me $10-20/each, I'm fine with that. For the same price as all of the grinders together, I could buy one "high-quality name brand" grinder. If anybody is concerned with how I could burn out 4 or 5 of them and still be happy with the quality, the ones I burned out were destroyed while I was building a full steel Hummer and the all aluminum Hummer. Each of those was full size and had a LOT of welds and tube which needed dressing. While I wouldn't trust having only one of these grinders, the price easily allows you to have one or two ready for use with a spare waiting for it's turn. As with the bandsaw, the low price really pushed the grade higher than the quality alone would deserve: Grade:

Here's a luxury - a 48" Pan & Box Brake

It works well for thinner sheet, but really starts to struggle if you're trying a full-width sheet in thicker gauge. It bends aluminum sheet easily. Overall, it's a bit of a pain to get set up properly, and I think I ruptured a testicle trying to move it, but if all you plan to bend is thinner gauge sheet, it works well. Grade:

Following is something you can NEVER have enough of: bar clamps!
http://www.harborfreight.com/cpi/ctaf/d ... mber=46809
I picked up a large stack of sizes from 6" to 24" and they've come in very useful as you would expect. I've got a couple of expensive clamps which work the same and which can be released from clamping pressure more easily, those expensive clamps cost me $25 or so each, compared to the $3-5 per clamp I spent for these. The thing I really like about the HF clamps is that they're cheap, and if I break one or melt the pads while welding, it's not a big loss. Overall, I have nothing to complain about with these clamps. Grade:
A
I have a ton of other HF tools, but no time to really go through and do a review on each at this time. If this thread stays alive, I'll post more as time permits.
