Wirelss router range extender ?

I use the following router:

NETGEAR WGR614 IEEE 802.3, IEEE 802.11b/g Wireless Router


I need to extend my range within my home. What would be a very good
repeater to use ?

Has anyone here used a repeater with this router ? I would prefer to use a
Netgear repeater (stay with same brand), but I am confused when I look at
their products, and don't know how to choose.

I will appreciate any comments !!
