Legal Encoders

Just about any encoder is legal. What specific encoders were you considering?

As Ether said, anything that follows rules for power draw is legal. Lots of teams use the USDigital E4T/P 4X encoders. Lots of Andymark products have the holes/shafts cut to hold these encoders, including the Toughboxes and the RAW box. Not terribly expensive either, coming in at $42.00.

AMT 102 and AMT 103 are great. Look on Digikey for them. They come with a full set of collars for shaft sizes up to 8mm, along with a neat box. VEry cheap, around $25 each.
You can use continuous potentiometers as absolute encoders in some cases. They come as cheap as $15 on Digikey. Regular potentiometers can work but have reduced angle range.
We have used Us Digital encoders, which are not terribly expensive but are still far more expensive and fragile IME than the AMTs.
You can also make your own encoders, but it takes some work. I recommend AMS for the chips if you are interested in going that route.
