Problem with trying cabs is that you can't really try them under gig conditions and volumes. I have a Genz NeoX212 and love it to bits, does everything I need it too ! Buy a used cab, let someone else toake the 'hit' and if you come to sell it you'll get your money back
There you go ... £450 you cant go wrong !
