Replying to Agressive inlinle skates

I want to get into inline skating in the off season for something to do but I don't know anything about them at all if it's possible could I buy a pair for 50-80 usd? If I have to I can go to $100 could you link some for me to look at? If it helps I'm size 9.5. What company's should I look at? Also if I want to make a rail to practice on how could I do that? Would thin pvc pipes work? If there's any typos I blame it on autocorrect...
