I'd make a couple of suggestions:
- for a 1/2" drive, buy a long-handled ratchet. I personally like the fixed handles over the flex ones, I have a 15" long one that's just feels right to me.
- the UltraPro stuff from NAPA in Canada is actually pretty good - I think the new 90 tooth ratchets they have may even be the same as Carlyle. Take a look at those. If you watch their sales you can probably find one for a good price.
- Princess Auto has a long 1/2" flex going on sale shortly - I just got the flier, I think it was Titan brand. They also have some fixed head ones available that I think you'd find a significant upgrade.
- watch Amazon - I've seen a few Williams items for reasonable prices.
My long 1/2" is only a 36 tooth, which I find adequate, as when I need to work in tighter spaces I usually use 3/8".
