I was just in there today. Not for anything special, just a tarp and whatever else caught my attention (had a 25% coupon burning a hole in my inbox). I ended up with $20 worth of odds and ends, but no tools. I did fondle a number of their ratchets and notes they felt pretty good.
Tool-wise, I have a set of 6-ton jackstands (the minimum size tall enough for my 4Runner without building a pier of 2x4s), their heavy duty low profile floor jack (heavy beast, but stable and strong), a low profile creeper, and an air ratchet. Of all of that, only the air ratchet has disappointed me. It's noisy and slow. I bought it for spots too tight to turn a manual ratchet, but I seldom use it. At a whopping $10, I didn't expect much.
At 45yo and having worked on my own cars and stuff since I was a teen, I have a pretty decent set of tools. These days, I mainly find myself buying specialty stuff. However, as the quality at HF improves, I'll give them a fair shake.
BTW, that 15lb soda blaster is mighty tempting. Unfortunately, I don't have enough compressor for it. Mine is rated at 3.7cfm@90psi continuous, but you need 6cfm@90psi. I have an 8gal tank daisy-chained inline with the compressor, giving me 16gals of air, but you can run through that quick before the compressor kicks on, putting you back at the 3.7cfm rate. A consolation prize might be their portable media blaster. It needs much less cfm per the label. However, soda appeals to me because of the lower abrasiveness and environmental friendliness (reduced clean-up needs).
