mustardxsjado's are good for learning due to the large soul and negative plates. combine that with a freestyle frame and you will be a sliding monster.Might be a little pricey, but it will be easier to learn stuff.
everything is expensive it sucks. Plus you can never find what you need cause the only two big shops in the US never get anything from distributors. Or what you want just simply isn't made.
basics are easy, way easier than skateboarding. you might even be able to do a grind first try. hard stuff comes when you want to try a 360 into a one footed topside grind and and miss, rip your shin on the rail and then rib rack on the rail. probably a reason there's not too many people that are very good at lollerblading, the bails are awful if you miss a trick. even small ones.
