Written off - Insurance advice?

[spoonlamp]

Embarrassment and anger aside (I mis-judged a corner joining M3, J4, clipped an artic), I have written off my beautiful Fazer and the insurers have finally got back to me with an offer. It's £1,520 and will still have the £300 excess to come off 


Anyone have experience here? Do I have to take that? I paid £1,995 for it and it was in very good condition, about 23 thou miles...


Any help is appreciated, thanks.
