We can talk you through the splice. Alternatively, there are a few people here that can do it for you.
Remember- if a $60 piece of gear saves you a few minutes at 1 job, it only takes a couple jobs before it has paid for itself.
For most climbing aspects, the strength of a splice is of little value, since the knots are strong enough. But with rigging gear, you never really know how strong you'll want something to be down the road. The splice is worth it in this application.
My favorite balancer is an eye-eye sling prusiked onto a piece of rope. each end of the rope gets tied to the limb to be balanced. the prusik placement is for adjusting the angle of the dangle.
