How much does polish matter on this diamond? Need advise!

I have the opportunity to purchase this stone for $5800:

GIA
1.26 carat
VS2
Color I
Depth 62.3
Table 55%
Crown Angle 34.5
Pav Angle 40.6
No Flor
No Culet
Girdle Med to Thick 4%
Polish Good

Should I be concerned about the Polish grade? Symmetry grade? Price? I appreciate your thoughts very much.
