NForce 2 board are stable, fast and loaded with features (if you want to), but they are expensive as well. The cheapest NF2 based boards will probably be sold for prices around $100.
If you are looking for mainboards that can do DDR333 (PC2700), with a Athlon XP (266) and nothing more, the Asus board you found at NewEgg will do.
The only feature you mentioned this board doesn't have is AGP8x, but there is no reasonable reason to buy a board because of the AGP8x bus right now. Even the fastest cards (Radeon 9800Pro etc) don't benefit from the AGP8x bus. AGP8x can handle faster transfers, but as there are no cards yet that fully use the bandwith of the AGP4x bus, there is no reason to go to 8x (this is pure marketing).
Buying such an "old" board has one big disadvantage: upgrading will become impossible or very expensive quite soon....
