Good router bits that people can actually afford are :
CMT, Frued, Amana, Whiteside, Katana by MLCS are fantastic and a great price, Eagle makes some awesome bits and the Price Cutter line is the best of the lower end quality bits.
The Festool bits are so outrageously priced I do not know anyone that has an extensive set of them. There are some Festool bits that are marked 100.00 and no kidding Eagle sells them for 1/2 that, in one case on sale a few of the Festool bits cost only 20.00 at Eagle and the quality was fantastic. Festool just never has sales like that. I get most of my bits when they go on sale.
If you are starting out and want a great quality, but do not have a ton of money I would start with the Katana bits. I have Amana bits that are so good I will never wear them out and they are just overkill for me.
The bits you use most get the best money can buy, the bits you use once in awhile you can get away with the Price Cutter brand no problem. Most of my bits are the higher end, a lot of Whiteside, but for a hobbyist I just do not see the need for a 120.00 chamfer bit from Amana or for most of the Festool bits.
I guess the best reason to get the Festool bits is for the 8mm shaft, but in real world conditions there is nothing wrong with the 1/4" bits no matter what the books say about them.

In-Tech Insert Knive System by Amana are neat and worth a good look:

Any of these bits from any of these companies will serve you well. If you mix brands and and look for sales you will get a better collection at a better price than sticking to one brand.
