think that covered it oh, one thing that tiffer didn't really mention was they are pretty cheapCheap,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...
Someone called me...... Egg's nothing wrong with them i still have one as a "third" back up & had this for 2 years now & a "VLocity" as the second back up, as now I'm using the Manga....I was writing it @ the same time,I just type slower and you know I will sing the praises of eggs,as will Cliff.....and they're so....
