help progressing!

right so ive been unicycling for about a year. I can ride pretty much for as far as I want but am really limited when it comes to tricks. I practise in the woods which really helps with balance and stuff because theres tree roots and pot holes and stuff so im a fairly confident rider. But I dont know where to go from there.

I can bunny hop small amounts but my uni is kinda crappy so not very good. Would it be worth buying a trials uni do you think?
Can turn confidently, ride backwards a few revolutions but thats bout it.

Any help would be greatly appreciated. videos would help loads as well thanks.
