Unless you want to mill your own mounting holes for the gearbox you are practically forced to use the $300 3-cim ballshifter, so although the build quality will be really good you will be spending some money.

Have you looked at the WCP SS gearboxes? They are about $120 for a 3CIM gearbox,that is high quality, lightweight and natively Versa-chassis compatible:

I disagree with you about cost, the VERSA-chassis will be about $780 with everything minus wheels for 8 wheels. If you are wanting to use the Andymark chassis with 8 wheels, you will need to purchase the upgrade kit which costs $300 and allows you to use 8 6inch higrip wheels. This means the total cost for the Andymark chassis is $899( Keep in mind the $599 KOP bit)
In comparison, you can make a Versa-chassis with 8 6 inch traction wheels for about $860, so roughly the same cost. But the Versa-chassis is way more versatile and you can use the same parts next year, and the year after, which you can't do at all with the KOP chassis.
If you learn how to make a WCD chassis in the off-season you can opt-out of the KOP, receive a $450 PDV from Andymark, which you can buy anything from Andymark with and be able to build a really good chassis next year, which will give you so many more options when designing your robot next.
