I have the
Ofna Hex Driver Set in both metric and standard. I like them for the money but I'm also considering another set. One thing that I want is to have the size of the hex driver scribed on the handle. I know that's a petty thing to be concerned with but I don't know what size any of my screws are and it's because my wrenches don't have the size on them.
When I'm wrenching on my son's car I'm always saying "grab me the silver hex wrench, now the blue" and so on.
One comment I will make is when I first got into RC (Nov last year) I stripped a .050 hex wrench (the Ofna one) and they offer a lifetime replacement warranty. I did pay $3.50 for shipping (total to them and back to me) but they were very quick to replace the bit.
At the track I've used some of the Trinity wrenches that you pictured and they felt very good in my hand. The price was a bit more than I wanted to spend ( I think 13-15 each?) but I may order my most commonly used ones.
As far as nut drivers I picked up a set of the Hobbico/Duratrax ones which are VERY cheap. They do the job but you must realize that they don't work in all situations. Due to their cast pot-metal construction they have a very thick sidewall which means that in tight spots the wrench may be to thick to work. They also aren't very deep so when you go to install or remove a ball stud it may bottom out in the nut driver before going completly over the hex area making installation/removal impossible.
Let us know what you decide to go with. I'm also continually looking for the best bang for the buck. I don't want to sacrifice any quality though so I'm leaning on spending some good money.
