I recently picked up a 72 (?) piece set of Yonico's. So far I'm pleased with their performance. Yes, they fall into the budget category, but here's my thinking: I have a full set of bits, so when I need that weird shape I normally wouldn't have, I have it. When the commonly used bits break/wear out, or I just need to get a better one, I can order the higher end ones specifically. Like a flush trim bit, once I determine I need a better one, I will have no problem dropping the cash for a good one. But I'm going to be very hesitant to buy a high end multi faceted Ogee round over, as I will rarely use it, but I'll be glad I have one on hand when I do need one.
One slight downside to the Yonico's, the "stem" of the bits are a bit short, so getting them to protrude up from a thick router table surface might be an issue. But in the router itself, I have had no problems.
