Cheap,reliable,cheap,easy to fix,cheap,easy to get parts for and cheap.
Go for a Z-boarder if you can or an egg 3(z-board std),the only issue I found with the y-board was when my Ego was ramping.
I personally prefer them over Halo's and most other hoppers and I've tried them all,now replaced with a Vlocity but always got an egg as a spare/lender.
For £30 you should get a z-boarder with the battery conversion(no more broken doors),£25 should get you a clean y-boarder...oh and they're cheap...
