Guys:

MSRP is $157, but we all know it never sells for that, right? But look at the prices of the components:

0115300 : S Parts: 53447 - Price: $12.00
1050018 : Instructions: 53447 - MSRP: $5.75; Discount Price: $1.26
7255028 : GFS Receiver Unit: 53447 - MSRP: $89.00 ; Discount Price: $21.50
7255029 : GFS Base: 53447 - Price: $37.00
7255030 : Infrared LED: 53447 - Price: $11.00
9415754 : Infrared LED Bag: 53447 - Price: $20.50

Just the components come doen to $103.25... and even those never sell at the set price.

And mebbe a thought, if you need all but the casing, mebbe Karen would remove it from one and sell ya the rest, keeping the case as a spare.
