well, since i wrench daily, i'll chime in...
about 60% Snap On, 20% Craftsmen and 20% other assorted not often used stuff..
there are certain tools that can't touch Snap On. ratchets, screwdrivers, sockets, wrenchs, punch and chisels...
my metric wrenchs are Craftsmen and 1 1/8 up to 2". tho a Craftsmen wrench is fine for most jobs, there are circumstances in my job where the slightly sleeker head, handle, etc of a Snap On is a big plus..
flank drive and the other Snap On tech is an improvement over standard Craftmen, Husky stuff, there is a difference.. for the weekend warrior its no biggie, but when you do it for a living, it matters..
i have a few Mac, but no Matco.. Mac is just as pricey pretty much as Snappy, so i figure might as well get the Snappy.. if he has something interesting, i'll consider it. mostly our Mac guy sells lots of other brand stuff.. usually i look to him for creepers, oddball stuff..
i'm particular about various pliers too.. my bud bought this 20 set from mac for $200. they suck... my Snap On dykes, needlenose, crimpers, etc blow them away.. Klein makes some nice crimpers, etc...
vise grip brand is all i'll own for their namesake... i have about 30 from regular plier types to every large body/welding ones you can imagine a few times over.. i made the mistake of picking up some cheapies at the swapmeet one year. what garbage, they start flexing off to the side and stuff.. gave em away to an apprentice..
air tools are a pretty wide assortment and i have just about everything you could possibly think of except 3/4 and 1" impact.. flange tools, shears, nibblers, air saw, air ratchets, 3/8 and 1/2 impacts.. every body grinder you can think of, angle and straight die grinder, air hammers, longboards (hutchins rule).. those breakdown about 50% Snappy, with the rest being a mix of mac, IR, some CP and FP....
oh, and toolbags are a HUGE part of my repertoire..
Ebay rules for Snap On.. you can generally get most stuff for about 1/2 what ya pay on a truck... most of my stuff is long payed for, but i do keep a small running account on the truck for occasional stuff i fancy... next toy will more than likely be a boroscope... then a bender...
my rig for those who haven't seen it...
