I had one of the first TR280's and found it excellent quality finish and design,I think the finish is better than the other makes available. 
also very easy to ride and does grip better than anything else i have ridden before. 
Have a Fajardo Replica now but have not had the chance to ride it yet to compare. 
I think the main issue with Ossa in the UK is the distribution/import with no real back up and marketing that seems to be non existent but then again they have only just got electrickery up north
