I guess skateboard general?

Considering getting a skateboard to help me get around for my job.

While I would love to get a bike, it does not fit well for Car pools/Buses, So ya.

Basically is building my own from parts best?

How much does a decent skate board cost, do I need to spend more than 50 bucks for something decent? only ever bought the cheapest off the shelf stuff.

I only need it for riding, probably going to get something compact so it can fit into my bag/on my bag

Do they make security trucks with a loop for locking it up to something?

Thanks /n/.
