Thanks for the link. Nice to know you can just send them to sunex for warranty. I trust that more than tooltopia.
No problem I did a lot of research on sets, ended up buying a Craftsman set but that 26 piece Sunex deep was the one I had settled on after going back and forth. On a side note, Sunex does use USA built presses to make their tools. Might make you feel a little better

.
Before ordering I would also call them and ask questions, maybe even pretend you want to warranty a socket, etc. Also you must give proof of purchase (receipt).

ToolTopia might also warranty the Sunex sockets too, and they have been in business for many years, so either way you should be OK. I'm not employed by Sunex, and both GP and Sunex get good reviews on here.
Something to consider, I bought the 52 piece Craftsman set for $171 + tax yesterday, and can sell off the SAE stuff for around $85 on ebay, and sell the short MM for around $50, so I got 12-19, 21, 22, 24, and 27 plus 3 extensions and a universal joint for $50 lifetime guarantee from Sears. Just something to consider, if you want bigger ones too HF sells a 29-38 axle nut set for $45 after 20% coupon, which are locally warrantied.
I figure *IF* I need a 20, 23, 25, or 26 mm at one time I can always buy it, and I still come out ahead.
