I'll estimate...keep in mind that I come as a family unit:

2 Specialized Expeditions @ $350 = $700
Helmets and other accouterments = $200
2 Specialized Allez @ $700 = $1400
1 Diamondback Octane @ $280
1 Specialized Sirrus (Flat trade for Expeditions) = $0
1 EZ Sport @ $1200
Total of 14 Pair of shorts @ $25 (avg.) = $350
4 pair of gloves = $45
Misc. Jersies, est. = $250
Racks, bags, etc, est. = $120
Pedals and shoes specific for cycling = $120
Tools, tubes, etc., est = $200

= $4865, and I'm sure that's short, but that's also 2 adults and 2 kids. The wife has moved to the bent, son has moved to her Allez, and daughter has moved to his Sirrus. So the Diamondback...well she still likes to ride it around the house.
