I decided to try something different and build a belt drive board. The total cost varies a bit depending on where you buy everything but it should be around $300 or less. The weight of the board with batteries is a little over 11 lbs.

Here are the parts:

ESC with remote (10S voltage, belt motor/brushless motor):

Other motor mount option (I use this on my newest belt-drive board - may require grinding the trucks):

This is just the mount:

Trucks (9” requires grinding):

Trucks (10” shouldn’t require grinding):

I used these FS 150mm trucks with the ebay motor mount on my newer build. I needed to grind them similarly to trucks in this video:

skateshred.com also has other skateboard stuff like hardware, risers, and a skate tool.

These bearings are decent:

5Ah battery option

The price and availability of LiPo batteries seems to fluctuate. Check around the internet from time to time to see what’s on sale. I would recommend 5S voltage with 3Ah or more capacity.
