Around here Silver is $56, Reposado is $58, and Anejo is $63
Price reflects the amounts it is aged in oak, for a newbie I'd start out with silver.
If this is too rich for your blood try some Don Julio or some Milagro.
If it's too strong for your tastes, pick up some Agavero and put a splash in the Tequila
BTW-I was drinking some Casa Noble ($87) last weekend, that might be the smoothest Tequila I ever drank. It was almost sweet.
