My work horse set is the same Maurice shows above (for under US$100 at ofrei). It does all I need and more. No need to go further down money lane.
As a side note, I also own a mix and match assortment of Horotec, A+F and original Bergeon (round top, brass body) drivers some with the fancy tip and/or brass tips. Needless to say I hardly use them although sometimes they see some light action. Of all of them, the original Bergeon is the least I like since it tends to roll when I put it down. They are all good and/or professional quality and no matter which you get they will do a good job. All take the higher quality Bergeon and Horotec blades and have good handling. I'm kind of partial for the Bergeon set above maybe out of using it so much.
I wouldn't doubt that the Horotec set Lawson talks about is superior and more durable due to the construction. It will also take all sorts of quality blades from different vendors too.
Cheers,
Bob
