My experience with TSC and the chinese made Champion wood splitter was not good. TSC didn't want to take any part in standing up for me as a customer who bought the bad product from them. They told me to take it up with Champion as they had only sold me the product and were not warranteeing it. In my opinion a good retailer will stand up for their customers and demand suppliers stand behind their products.
Most everything we buy has Chinese or Japanese parts in it- you can't get away from that. I had Sears replace my old USA-made 1/2" ratchet (they wouldn't give me the guts, just replace it), and the replacement was made in China. It isn't China's fault that TSC won't back up the splitter, it is TSC's. I love the place, and my local store is pretty fair about things. But, they don't know their head from a hole in the ground when you ask anything product specific, and like many companies (Lowe's comes to mind as one), the warranty is on the manufacturer, not them. You run the risk of having to jump hurdles to get warranty work done, and have to pay the shipping. And, they all lose- I would think twice about buying a Champion splitter, from TSC or anywhere else.
My dad bought a Northstar from Northern Tools, and it has been fantastic. I'm sure it has foreign parts- it is Honda powered, for one thing. But, when we had a problem (someone "borrowed" the splitter, and broke some things. That is another story), Northern had the parts to us fast. We had to pay, because it wasn't their fault; but, the turnaround was quick. I just bought a die grinder from them on their Ebay store, and it arrived non-functional. The Ebay policy was that I had to pay to ship it back. I traveled to Lynchburg, VA at the beginning of the week for business, and they have a Northern store. I explained to them what was going on, including the Ebay policy, and they said no problem; they exchanged it, and the replacement is good. By the time I got home, Northern had issued me a reimbursement check for it. They were on the ball, both accounts. The point is, we can't get too far away from Chinese and other foreign stuff- that's the way it is now. But, businesses do need to step it up in how they represent the products. We have to go out on a limb to buy it, they have to go out on a limb to back it better. We have put ourselves in a place that won't change, so we all have to make it work. In the end, they can sell and we can buy better products from foreign manufactures, if we both demand it.
