The Craftsman sets goes to 30mm. But the socket sets don't include a ratchet. Still, you're not going to get 1/5 of that Craftsmans set, even if you don't use all of it, it's a good value.
This is where the valuse in a cheap set or a Sears set really shines. Its in the stuff you don't use. I got a lot of metric stuff I don't use, some pieces probably never, could get by easily without a lot of it but tat that cost it hasn't hurt and a wrench a guy has 5$ in to he doesn't use is way better than 55.
I did the same as a couple other guys here and elsewhere. When we were hurting bought big cman sets to get going and cover the bigger basics, always figured if t didn't work wasn't out much for that piece and would improve it. It was more expensive in the day, Sears has dropped to near disposable pricing. While 7500 seems like a lot it would be free and clear at less than a hundred a week to the truck in a couple years.
Its something I would consider if I needed a but load of larger sizes, tap sets etc I didn't already have and wanted to add another layer of duplication, cheaper than a hi priced warranty,,, which it has anyway,,, but at a buck a socket who cares although replacement singles are priced higher.
There are a lot of small business that would gain immediate payback for splurging on a 309 piece set, actually any of the sale sears sets. I go places where the hand tools are pitiful. I know that sounds like an argument that may be contradictory from other ramblings but its not. A big reason I love cheap tools,,,,,,,,,,,, its a no brainer to buy a wrench to get something done. Our battery packs are going south, its going to be pricey but I can "feel" the drag and it will only get worse.
I can feel a shortage of channelocks and razor knives and combo wrenches (and it don't matter how good and what brand) but a shortage in numbers where its leading to inconvenience and adding a complication which could be solved with the investment of a 1.50 combo wrench tossed in a tool box.
What began way back in the day with cheap tools has evolved as the quality went up. Many pieces originally intended for that use have "migrated" in to general service where they became invisible and highly used.
This is where I get the real world view,,, is it good enough, do we break one every day, how many we lose, do they stand up to long term continual use and while i imagine you can find some failures and could find some really cheap stuff if you looked hard enough the fear and risk is highly exaggerated, super inflated, a bet that makes the casino or a lottery ticket look appealing.
And those are retail prices, which better come down like a prom dress when you start waving bills and offering multi-thousand-dollar prepaid sales. 
But yes, SO is in fact expensive... even at a discount.
1400ish is a lot of tools, but $7500 is a lot more money. Better be some heavy hitters in there to make up for the $1 a pop sockets, $0.10 hex keys, etc...
