My Dad has one of these unis, and I have ridden it a few times.
It would be fine for a cheap learner uni, the only problem with it is
the 140mm cranks it comes with (not mentioned on ebay). These make it a
very twitchy ride and would probably be horrible for learning, so new,
shorter cranks (from unicycle.com) would add about another £10 to the
cost. SJS Cycles is also a trustworthy ebay seller in my experience.
If you want to do trials, however, you will need a more expensive uni.
This one has a narrow tyre with with very little bounce, no handle on
the seat, and most importantly, a cheap square taper hub that I
personally would not even use for hopping on the spot, let alone off
drops.
Trials unis are pretty expensive (but still very good value), so you
have a choice of spending a little now and a lot later (presuming you
stick with unicycling), or spending a lot now and nothing for quite a
while.
You might want to post on the Trading Post board to ask if anyone has a
20" to sell at the moment, whether it's one like this or a trials you
will still get a better price secondhand.
P.S. I'm assuming from the eBay link that you live in the UK. If you
are actually in the US then do what trials_uni said and get a Torker
DX, these are
cheap, have a great reputation, but unfortunately are not available in
the UK!
